+This is a PostgreSQL adapted version of the timezone library
+from:
+ftp://elsie.nci.nih.gov/pub/tz*.tar.gz
+
+
+The interface is used when USE_PGTZ is defined at the top level. This
+will cause the following functions to be redefined:
+ localtime pg_localtime
+ gmtime pg_gmtime
+ asctime pg_asctime
+ ctime pg_ctime
+ difftime pg_difftime
+ mktime pg_mktime
+ tzset pg_tzset
+
+and the TIMEZONE_GLOBAL define in c.h is redefined to pg_timezone.

+
+# This data is by no means authoritative; if you think you know better,
+# go ahead and edit the file (and please send any changes to
+# tz@elsie.nci.nih.gov for general use in the future).
+
+# From Paul Eggert <eggert@twinsun.com> (1999-03-22):
+#
+# A good source for time zone historical data outside the U.S. is
+# Thomas G. Shanks, The International Atlas (5th edition),
+# San Diego: ACS Publications, Inc. (1999).
+#
+# Gwillim Law writes that a good source
+# for recent time zone data is the International Air Transport
+# Association's Standard Schedules Information Manual (IATA SSIM),
+# published semiannually. Law sent in several helpful summaries
+# of the IATA's data after 1990.
+#
+# Except where otherwise noted, Shanks is the source for entries through 1990,
+# and IATA SSIM is the source for entries after 1990.
+#
+# Another source occasionally used is Edward W. Whitman, World Time Differences,
+# Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
+# I found in the UCLA library.
+#
+# A reliable and entertaining source about time zones is
+# Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).
+#
+# Previous editions of this database used WAT, CAT, SAT, and EAT
+# for +0:00 through +3:00, respectively,
+# but Mark R V Murray <markm@grondar.za> reports that
+# `SAST' is the official abbreviation for +2:00 in the country of South Africa,
+# `CAT' is commonly used for +2:00 in countries north of South Africa, and
+# `WAT' is probably the best name for +1:00, as the common phrase for
+# the area that includes Nigeria is ``West Africa''.
+# He has heard of ``Western Sahara Time'' for +0:00 but can find no reference.
+#
+# To make things confusing, `WAT' seems to have been used for -1:00 long ago;
+# I'd guess that this was because people needed _some_ name for -1:00,
+# and at the time, far west Africa was the only major land area in -1:00.
+# This usage is now obsolete, as the last use of -1:00 on the African
+# mainland seems to have been 1976 in Western Sahara.
+#
+# To summarize, the following abbreviations seem to have some currency:
+# -1:00 WAT West Africa Time (no longer used)
+# 0:00 GMT Greenwich Mean Time
+# 2:00 CAT Central Africa Time
+# 2:00 SAST South Africa Standard Time
+# and Murray suggests the following abbreviation:
+# 1:00 WAT West Africa Time
+# I realize that this leads to `WAT' being used for both -1:00 and 1:00
+# for times before 1976, but this is the best I can think of
+# until we get more information.
+#
+# I invented the following abbreviations; corrections are welcome!
+# 2:00 WAST West Africa Summer Time
+# 2:30 BEAT British East Africa Time (no longer used)
+# 2:44:45 BEAUT British East Africa Unified Time (no longer used)
+# 3:00 CAST Central Africa Summer Time (no longer used)
+# 3:00 SAST South Africa Summer Time (no longer used)
+# 3:00 EAT East Africa Time

+#
+# From Lee Hotz (2001-03-08):
+# I queried the folks at Columbia who spent the summer at Vostok and this is
+# what they had to say about time there:
+# ``in the US Camp (East Camp) we have been on New Zealand (McMurdo)
+# time, which is 12 hours ahead of GMT. The Russian Station Vostok was
+# 6 hours behind that (although only 2 miles away, i.e. 6 hours ahead
+# of GMT). This is a time zone I think two hours east of Moscow. The
+# natural time zone is in between the two: 8 hours ahead of GMT.''
+#
+# From Paul Eggert (2001-05-04):
+# This seems to be hopelessly confusing, so I asked Lee Hotz about it
+# in person. He said that some Antartic locations set their local
+# time so that noon is the warmest part of the day, and that this
+# changes during the year and does not necessarily correspond to mean
+# solar noon. So the Vostok time might have been whatever the clocks
+# happened to be during their visit. So we still don't really know what time
+# it is at Vostok. But we'll guess UTC+6.

+# One last quirk about South Pole time.
+# All the electric clocks are usually wrong.
+# Something about the generators running at 60.1hertz or something
+# makes all of the clocks run fast. So every couple of days,
+# we have to go around and set them back 5 minutes or so.

+# Peking (Bejing) time zone was recognized. Since that date, China

+# The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
+# based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
+# of the Country's Organization for Official and Employment Affairs,
+# and referring to the law for equating the working hours of workers
+# and officers in the whole country dated 1359/4/23 [1980-07-14], and
+# for synchronizing the official times of the country, agreed that:
+#
+# The official time of the country will should move forward one hour
+# at the 24[:00] hours of the first day of Farvardin and should return
+# to its previous state at the 24[:00] hours of the 30th day of
+# Shahrivar.
+#
+# First Deputy to the President - Hassan Habibi
+#
+# From personal experience, that agrees with what has been followed
+# for at least the last 5 years. Before that, for a few years, the
+# date used was the first Thursday night of Farvardin and the last
+# Thursday night of Shahrivar, but I can't give exact dates....
+# I have also changed the abbreviations to what is considered correct
+# here in Iran, IRST for regular time and IRDT for daylight saving time.

+# Israel
+
+# From Ephraim Silverberg (2001-01-11):
+#
+# I coined "IST/IDT" circa 1988. Until then there were three
+# different abbreviations in use:
+#
+# JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
+# IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
+# EEST Eastern Europe Standard Time [used by almost everyone else]
+#
+# Since timezones should be called by country and not capital cities,
+# I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
+# EEST was equally unacceptable. Since "zonal" was not compatible with
+# any other timezone abbreviation, I felt that 'IST' was the way to go
+# and, indeed, it has received almost universal acceptance in timezone
+# settings in Israeli computers.
+#
+# In any case, I am happy to share timezone abbreviations with India,
+# high on my favorite-country list (and not only because my wife's
+# family is from India).

+# (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17 and 2000-07-25):
+
+# According to the Office of the Secretary General of the Ministry of
+# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
+# One thing is entrenched in law, however: that there must be at least 150
+# days of daylight savings time annually. From 1993-1998, the change to
+# daylight savings time was on a Friday morning from midnight IST to
+# 1 a.m IDT; up until 1998, the change back to standard time was on a
+# Saturday night from midnight daylight savings time to 11 p.m. standard
+# time. 1996 is an exception to this rule where the change back to standard
+# time took place on Sunday night instead of Saturday night to avoid
+# conflicts with the Jewish New Year. In 1999, the change to
+# daylight savings time was still on a Friday morning but from
+# 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
+# was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
+# 1999 only. In the year 2000, the change to daylight savings time was
+# similar to 1999, but although the change back will be on a Friday, it
+# will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
+# changes to/from will take place at 1 a.m. old time, but now there is no
+# rule as to what day of the week it will take place in as the start date
+# (except in 2003) is the night after the Passover Seder (i.e. the eve

+# Today's _Asahi Evening News_ (page 4) reports that Japan had
+# daylight saving between 1948 and 1951, but ``the system was discontinued

+# The law is enacted on 1886-07-07.
+
+# From Hideyuki Suzuki (1998-11-16):
+# The ordinance No. 51 (1886) established "standard time" in Japan,
+# which stands for the time on E 135 degree.
+# In the ordinance No. 167 (1895), "standard time" was renamed to "central
+# standard time". And the same ordinance also established "western standard

+#
+# I wrote "ordinance" above, but I don't know how to translate.

+# Palestine
+
+# From Amos Shapir <amos@nsof.co.il> (1998-02-15):
+#
+# From 1917 until 1948-05-15, all of Palestine, including the parts now
+# known as the Gaza Strip and the West Bank, was under British rule.
+# Therefore the rules given for Israel for that period, apply there too...
+#
+# The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
+# (except a short occupation by Israel from 1956-11 till 1957-03, but no
+# time zone was affected then). It was never formally annexed to Egypt,
+# though.
+#
+# The rest of Palestine was under Jordanian rule at that time, formally
+# annexed in 1950 as the West Bank (and the word "Trans" was dropped from
+# the country's previous name of "the Hashemite Kingdom of the
+# Trans-Jordan"). So the rules for Jordan for that time apply. Major
+# towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
+# East Jerusalem.
+#
+# Both areas were occupied by Israel in June 1967, but not annexed (except
+# for East Jerusalem). They were on Israel time since then; there might
+# have been a Military Governor's order about time zones, but I'm not aware
+# of any (such orders may have been issued semi-annually whenever summer
+# time was in effect, but maybe the legal aspect of time was just neglected).
+#
+# The Palestinian Authority was established in 1993, and got hold of most
+# towns in the West Bank and Gaza by 1995. I know that in order to
+# demonstrate...independence, they have been switching to
+# summer time and back on a different schedule than Israel's, but I don't
+# know when this was started, or what algorithm is used (most likely the
+# Jordanian one).
+#
+# To summarize, the table should probably look something like that:
+#
+# Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
+# ------------+-----------+-----------+-----------+-----------
+# Israel | Zion | Zion | Zion | Zion
+# West bank | Zion | Jordan | Zion | Jordan
+# Gaza | Zion | Egypt | Zion | Jordan
+#
+# I guess more info may be available from the PA's web page (if/when they
+# have one).
+
+# From Paul Eggert (1998-02-25):
+# Shanks writes that Gaza did not observe DST until 1957, but we'll go
+# with Shapir and assume that it observed DST from 1940 through 1947,
+# and that it used Jordanian rules starting in 1996.
+# We don't yet need a separate entry for the West Bank, since
+# the only differences between it and Gaza that we know about
+# occurred before our cutoff date of 1970.
+# However, as we get more information, we may need to add entries
+# for parts of the West Bank as they transitioned from Israel's rules
+# to Palestine's rules. If you have more info about this, please
+# send it to tz@elsie.nci.nih.gov for incorporation into future editions.
+
+# From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
+# forwarded by Ephraim Silverberg:
+#
+# Despite the fact that Israel changed over to daylight savings time
+# last week, the PLO Authority (PA) has decided not to turn its clocks
+# one-hour forward at this time. As a sign of independence from Israeli rule,
+# the PA has decided to implement DST in April.
+
+# From Paul Eggert (1999-09-20):
+# Daoud Kuttab writes in
+# <a href="http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html">

+
+# <a href="http://www.dstc.qut.edu.au/DST/marg/daylight.html">
+# Australia's Daylight Saving Times
+# </a>, by Margaret Turner, summarizes daylight saving issues in Australia.
+
+# From John Mackin (1991-03-06):
+# We in Australia have _never_ referred to DST as `daylight' time.
+# It is called `summer' time. Now by a happy coincidence, `summer'
+# and `standard' happen to start with the same letter; hence, the
+# abbreviation does _not_ change...
+# The legislation does not actually define abbreviations, at least
+# in this State, but the abbreviation is just commonly taken to be the
+# initials of the phrase, and the legislation here uniformly uses
+# the phrase `summer time' and does not use the phrase `daylight
+# time'.
+# Announcers on the Commonwealth radio network, the ABC (for Australian
+# Broadcasting Commission), use the phrases `Eastern Standard Time'
+# or `Eastern Summer Time'. (Note, though, that as I say in the
+# current australasia file, there is really no such thing.) Announcers
+# on its overseas service, Radio Australia, use the same phrases
+# prefixed by the word `Australian' when referring to local times;
+# time announcements on that service, naturally enough, are made in UTC.
+
+# From Arthur David Olson (1992-03-08):
+# Given the above, what's chosen for year-round use is:
+# CST for any place operating at a GMTOFF of 9:30
+# WST for any place operating at a GMTOFF of 8:00
+# EST for any place operating at a GMTOFF of 10:00
+
+# From Paul Eggert (2001-04-05), summarizing a long discussion about "EST"
+# versus "AEST" etc.:
+#
+# I see the following points of dispute:
+#
+# * How important are unique time zone abbreviations?
+#
+# Here I tend to agree with the point (most recently made by Chris
+# Newman) that unique abbreviations should not be essential for proper
+# operation of software. We have other instances of ambiguity
+# (e.g. "IST" denoting both "Israel Standard Time" and "Indian
+# Standard Time"), and they are not likely to go away any time soon.
+# In the old days, some software mistakenly relied on unique
+# abbreviations, but this is becoming less true with time, and I don't
+# think it's that important to cater to such software these days.
+#
+# On the other hand, there is another motivation for unambiguous
+# abbreviations: it cuts down on human confusion. This is
+# particularly true for Australia, where "EST" can mean one thing for
+# time T and a different thing for time T plus 1 second.
+#
+# * Does the relevant legislation indicate which abbreviations should be used?
+#
+# Here I tend to think that things are a mess, just as they are in
+# many other countries. We Americans are currently disagreeing about
+# which abbreviation to use for the newly legislated Chamorro Standard
+# Time, for example.
+#
+# Personally, I would prefer to use common practice; I would like to
+# refer to legislation only for examples of common practice, or as a
+# tiebreaker.
+#
+# * Do Australians more often use "Eastern Daylight Time" or "Eastern
+# Summer Time"? Do they typically prefix the time zone names with
+# the word "Australian"?
+#
+# My own impression is that both "Daylight Time" and "Summer Time" are
+# common and are widely understood, but that "Summer Time" is more
+# popular; and that the leading "A" is also common but is omitted more
+# often than not. I just used AltaVista advanced search and got the
+# following count of page hits:
+#
+# 1,103 "Eastern Summer Time" AND domain:au
+# 971 "Australian Eastern Summer Time" AND domain:au
+# 613 "Eastern Daylight Time" AND domain:au
+# 127 "Australian Eastern Daylight Time" AND domain:au
+#
+# Here "Summer" seems quite a bit more popular than "Daylight",
+# particularly when we know the time zone is Australian and not US,
+# say. The "Australian" prefix seems to be popular for Eastern Summer
+# Time, but unpopular for Eastern Daylight Time.
+#
+# For abbreviations, tools like AltaVista are less useful because of
+# ambiguity. Many hits are not really time zones, unfortunately, and
+# many hits denote US time zones and not Australian ones. But here
+# are the hit counts anyway:
+#
+# 161,304 "EST" and domain:au
+# 25,156 "EDT" and domain:au
+# 18,263 "AEST" and domain:au
+# 10,416 "AEDT" and domain:au
+#
+# 14,538 "CST" and domain:au
+# 5,728 "CDT" and domain:au
+# 176 "ACST" and domain:au
+# 29 "ACDT" and domain:au
+#
+# 7,539 "WST" and domain:au
+# 68 "AWST" and domain:au
+#
+# This data suggest that Australians tend to omit the "A" prefix in
+# practice. The situation for "ST" versus "DT" is less clear, given
+# the ambiguities involved.
+#
+# * How do Australians feel about the abbreviations in the tz database?
+#
+# If you just count Australians on this list, I count 2 in favor and 3
+# against. One of the "against" votes (David Keegel) counseled delay,
+# saying that both AEST/AEDT and EST/EST are widely used and
+# understood in Australia.
+
+# From Paul Eggert (1995-12-19):
+# Shanks reports 2:00 for all autumn changes in Australia and New Zealand.
+# Mark Prior <mrp@itd.adelaide.edu.au> writes that his newspaper
+# reports that NSW's fall 1995 change will occur at 2:00,
+# but Robert Elz says it's been 3:00 in Victoria since 1970
+# and perhaps the newspaper's `2:00' is referring to standard time.
+# For now we'll continue to assume 2:00s for changes since 1960.

+# 50,000 sheep, about 100 kilometers long and 40 kilometers into the
+# continent. The primary town is Madura, with the other towns being
+# Mundrabilla and Eucla. According to the sheriff of Madura, the
+# residents got tired of having to change the time so often, as they are
+# located in a strip overlapping the border of South Australia and Western
+# Australia. South Australia observes daylight saving time; Western
+# Australia does not. The two states are one and a half hours apart. The
+# residents decided to forget about this nonsense of changing the clock so
+# much and set the local time 20 hours and 45 minutes from the
+# international date line, or right in the middle of the time of South
+# Australia and Western Australia. As it only affects about 10 people and
+# tourists staying at the Madura Motel, it has never really made as big an
+# impact as Broken Hill. However, as tourist visiting there or anyone
+# calling the local sheriff will attest, they do keep time in this way.

+# From Paul Eggert (2002-04-09):
+# This is confirmed by the section entitled

+# which says a few other things:
+#
+# * Border Village, SA also is 45 minutes ahead of Perth.

+# How Tonga became `The Land where Time Begins'
+# </a>:
+
+# Until 1941 Tonga maintained a standard time 50 minutes ahead of NZST
+# 12 hours and 20 minutes ahead of GMT. When New Zealand adjusted its
+# standard time in 1940s, Tonga had the choice of subtracting from its
+# local time to come on the same standard time as New Zealand or of
+# advancing its time to maintain the differential of 13 degrees
+# (approximately 50 minutes ahead of New Zealand time).
+#
+# Because His Majesty King Taufa'ahau Tupou IV, then Crown Prince
+# Tungi, preferred to ensure Tonga's title as the land where time
+# begins, the Legislative Assembly approved the latter change.
+#
+# But some of the older, more conservative members from the outer
+# islands objected. "If at midnight on Dec. 31, we move ahead 40
+# minutes, as your Royal Highness wishes, what becomes of the 40
+# minutes we have lost?"

+# to say your prayers in the morning."

+#
+# Saturday, the 14th [of October, 1950] -- ... The time was all the
+# more confusing at that point, because we had crossed the

+
+# The International Date Line
+
+# From Gwillim Law (2000-01-03):
+#
+# The International Date Line is not defined by any international standard,
+# convention, or treaty. Mapmakers are free to draw it as they please.
+# Reputable mapmakers will simply ensure that every point of land appears on
+# the correct side of the IDL, according to the date legally observed there.
+#
+# When Kiribati adopted a uniform date in 1995, thereby moving the Phoenix and
+# Line Islands to the west side of the IDL (or, if you prefer, moving the IDL
+# to the east side of the Phoenix and Line Islands), I suppose that most
+# mapmakers redrew the IDL following the boundary of Kiribati. Even that line
+# has a rather arbitrary nature. The straight-line boundaries between Pacific
+# island nations that are shown on many maps are based on an international
+# convention, but are not legally binding national borders.
+#
+# An Anglo-French Conference on Time-Keeping at Sea (June, 1917) agreed that
+# legal time on the high seas would be zone time, i.e., the standard time at
+# the nearest meridian that is a multiple of fifteen degrees. The date is
+# governed by the IDL; therefore, even on the high seas, there may be some
+# places as late as fourteen hours later than UTC. And, since the IDL is not
+# an international standard, there are some places on the high seas where the
+# correct date is ambiguous.

+# Britain (United Kingdom) and Ireland (Eire)
+
+# From Peter Ilieve <peter@memex.co.uk> (1994-07-06):
+#
+# On 17 Jan 1994 the Independent, a UK quality newspaper, had a piece about
+# historical vistas along the Thames in west London. There was a photo
+# and a sketch map showing some of the sightlines involved. One paragraph
+# of the text said:
+#
+# `An old stone obelisk marking a forgotten terrestrial meridian stands
+# beside the river at Kew. In the 18th century, before time and longitude
+# was standardised by the Royal Observatory in Greenwich, scholars observed
+# this stone and the movement of stars from Kew Observatory nearby. They
+# made their calculations and set the time for the Horse Guards and Parliament,
+# but now the stone is obscured by scrubwood and can only be seen by walking
+# along the towpath within a few yards of it.'
+#
+# I have a one inch to one mile map of London and my estimate of the stone's
+# position is 51 deg. 28' 30" N, 0 deg. 18' 45" W. The longitude should
+# be within about +-2". The Ordnance Survey grid reference is TQ172761.
+#
+# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.]
+
+# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
+#
+# Howse writes that Britain was the first country to use standard time.
+# The railways cared most about the inconsistencies of local mean time,
+# and it was they who forced a uniform time on the country.
+# The original idea was credited to Dr. William Hyde Wollaston (1766-1828)
+# and was popularized by Abraham Follett Osler (1808-1903).
+# The first railway to adopt London time was the Great Western Railway
+# in November 1840; other railways followed suit, and by 1847 most
+# (though not all) railways used London time. On 1847-09-22 the
+# Railway Clearing House, an industry standards body, recommended that GMT be
+# adopted at all stations as soon as the General Post Office permitted it.
+# The transition occurred on 12-01 for the L&NW, the Caledonian,
+# and presumably other railways; the January 1848 Bradshaw's lists many
+# railways as using GMT. By 1855 the vast majority of public
+# clocks in Britain were set to GMT (though some, like the great clock
+# on Tom Tower at Christ Church, Oxford, were fitted with two minute hands,
+# one for local time and one for GMT). The last major holdout was the legal
+# system, which stubbornly stuck to local time for many years, leading
+# to oddities like polls opening at 08:13 and closing at 16:13.
+# The legal system finally switched to GMT when the Statutes (Definition
+# of Time) Act took effect; it received the Royal Assent on 1880-08-02.
+#
+# In the tables below, we condense this complicated story into a single
+# transition date for London, namely 1847-12-01. We don't know as much
+# about Dublin, so we use 1880-08-02, the legal transition time.
+
+# From Paul Eggert (2003-09-27):
+# Summer Time was first seriously proposed by William Willett (1857-1915),
+# a London builder and member of the Royal Astronomical Society
+# who circulated a pamphlet ``The Waste of Daylight'' (1907)
+# that proposed advancing clocks 20 minutes on each of four Sundays in April,
+# and retarding them by the same amount on four Sundays in September.
+# A bill was drafted in 1909 and introduced in Parliament several times,
+# but it met with ridicule and opposition, especially from farming interests.
+# Later editions of the pamphlet proposed one-hour summer time, and
+# it was eventually adopted as a wartime measure in 1916.
+# See: Summer Time Arrives Early, The Times (2000-05-18).
+# A monument to Willett was unveiled on 1927-05-21, in an open space in
+# a 45-acre wood near Chislehurst, Kent that was purchased by popular
+# subscription and open to the public. On the south face of the monolith,
+# designed by G. W. Miller, is the the William Willett Memorial Sundial,
+# which is permanently set to Summer Time.
+
+# From Winston Churchill (1934-04-28):
+# It is one of the paradoxes of history that we should owe the boon of
+# summer time, which gives every year to the people of this country
+# between 160 and 170 hours more daylight leisure, to a war which
+# plunged Europe into darkness for four years, and shook the
+# foundations of civilization throughout the world.

+
+# From Paul Eggert (1996-09-03):
+# The OED Supplement says that the English originally said ``Daylight Saving''
+# when they were debating the adoption of DST in 1908; but by 1916 this
+# term appears only in quotes taken from DST's opponents, whereas the
+# proponents (who eventually won the argument) are quoted as using ``Summer''.
+
+# From Arthur David Olson (1989-01-19):

+# I remember reading in various wartime issues of the London Times the

+# </a>.
+
+# From Paul Eggert (2001-07-18):
+#
+# For lack of other data, we'll follow Shanks for Eire in 1940-1948.
+#
+# Given Ilieve and Myers's data, the following claims by Shanks are incorrect:
+# * Wales did not switch from GMT to daylight saving time until
+# 1921 Apr 3, when they began to conform with the rest of Great Britain.
+# Actually, Wales was identical after 1880.
+# * Eire had two transitions on 1916 Oct 1.
+# It actually just had one transition.
+# * Northern Ireland used single daylight saving time throughout WW II.
+# Actually, it conformed to Britain.
+# * GB-Eire changed standard time to 1 hour ahead of GMT on 1968-02-18.
+# Actually, that date saw the usual switch to summer time.
+# Standard time was not changed until 1968-10-27 (the clocks didn't change).
+#
+# Here is another incorrect claim by Shanks:
+# * Jersey, Guernsey, and the Isle of Man did not switch from GMT
+# to daylight saving time until 1921 Apr 3, when they began to
+# conform with Great Britain.
+# S.R.&O. 1916, No. 382 and HO 45/10811/312364 (quoted above) say otherwise.
+#
+# The following claim by Shanks is possible though doubtful;
+# we'll ignore it for now.
+# * Dublin's 1971-10-31 switch was at 02:00, even though London's was 03:00.
+#
+#
+# Whitman says Dublin Mean Time was -0:25:21, which is more precise than Shanks.
+# Perhaps this was Dunsink Observatory Time, as Dunsink Observatory
+# (8 km NW of Dublin's center) seemingly was to Dublin as Greenwich was
+# to London. For example:
+#
+# "Timeball on the ballast office is down. Dunsink time."
+# -- James Joyce, Ulysses
+
+# From Paul Eggert (1999-03-28):
+# Clive Feather (<news:859845706.26043.0@office.demon.net>, 1997-03-31)
+# reports that Folkestone (Cheriton) Shuttle Terminal uses Concession Time
+# (CT), equivalent to French civil time.
+# Julian Hill (<news:36118128.5A14@virgin.net>, 1998-09-30) reports that
+# trains between Dollands Moor (the freight facility next door)
+# and Frethun run in CT.
+# My admittedly uninformed guess is that the terminal has two authorities,
+# the French concession operators and the British civil authorities,
+# and that the time depends on who you're talking to.
+# If, say, the British police were called to the station for some reason,
+# I would expect the official police report to use GMT/BST and not CET/CEST.

+# The law governing time in Ireland is under Statutory Instrument SI 395/94,
+# which gives force to European Union 7th Council Directive # 94/21/EC.
+# Under this directive, the Minister for Justice in Ireland makes appropriate
+# regulations. I spoke this morning with the Secretary of the Department of
+# Justice (tel +353 1 678 9711) who confirmed to me that the correct name is
+# "Irish Summer Time", abbreviated to "IST".

+# From Paul Eggert (1996-11-22):
+# Greenland joined the EU as part of Denmark, obtained home rule on 1979-05-01,
+# and left the EU on 1985-02-01. It therefore should have been using EU
+# rules at least through 1984. Shanks says Scoresbysund and Godthab
+# used C-Eur rules after 1980, but IATA SSIM (1991/1996) says they use EU
+# rules since at least 1991. Assume EU rules since 1980.
+
+# From Gwillin Law (2001-06-06), citing
+# <http://www.statkart.no/efs/efshefter/2001/efs5-2001.pdf> (2001-03-15),
+# and with translations corrected by Steffen Thorsen:
+#
+# Greenland has four local times, and the relation to UTC
+# is according to the following time line:
+#
+# The military zone near Thule UTC-4
+# Standard Greenland time UTC-3
+# Scoresbysund UTC-1
+# Danmarkshavn UTC
+#
+# In the military area near Thule and in Danmarkshavn DST will not be
+# introduced.
+
+# From Rives McDow (2001-11-01):
+#
+# I correspond regularly with the Dansk Polarcenter, and wrote them at
+# the time to clarify the situation in Thule. Unfortunately, I have
+# not heard back from them regarding my recent letter. [But I have
+# info from earlier correspondence.]
+#
+# According to the center, a very small local time zone around Thule
+# Air Base keeps the time according to UTC-4, implementing daylight
+# savings using North America rules, changing the time at 02:00 local time....
+#
+# The east coast of Greenland north of the community of Scoresbysund
+# uses UTC in the same way as in Iceland, year round, with no dst.
+# There are just a few stations on this coast, including the
+# Danmarkshavn ICAO weather station mentioned in your September 29th
+# email. The other stations are two sledge patrol stations in
+# Mestersvig and Daneborg, the air force base at Station Nord, and the
+# DPC research station at Zackenberg.
+#
+# Scoresbysund and two small villages nearby keep time UTC-1 and use
+# the same daylight savings time period as in West Greenland (Godthab).
+#
+# The rest of Greenland, including Godthab (this area, although it
+# includes central Greenland, is known as west Greenland), keeps time
+# UTC-3, with daylight savings methods according to European rules.
+#
+# It is common procedure to use UTC 0 in the wilderness of East and
+# North Greenland, because it is mainly Icelandic aircraft operators
+# maintaining traffic in these areas. However, the official status of
+# this area is that it sticks with Godthab time. This area might be
+# considered a dual time zone in some respects because of this.
+
+# From Rives McDow (2001-11-19):
+# I heard back from someone stationed at Thule; the time change took place
+# there at 2:00 AM.
+
+# From Paul Eggert (2001-11-19):
+# The 1997 CIA map shows Danmarkshavn on GMT; the 1995 map as like Godthab.
+# For lack of better info, assume they were like Godthab before 1996.
+# startkart.no says Thule does not observe DST, but this is clearly an error,

+#
+# From Peter Ilieve <peter@aldie.co.uk> (1996-10-28):
+# [IATA SSIM (1992/1996) claims that the Baltic republics switch at 01:00s,

+# ``I do not [know] exactly but there are some little different

+# conversion in Sunday connected with end of summer time in Estonia....
+# A discussion is running about the summer time efficiency and effect on

+# I also asked [my relative] whether they use any standard abbreviation

+# Iceland
+#
+# From Adam David <adam@veda.is> (1993-11-06):
+# The name of the timezone in Iceland for system / mail / news purposes is GMT.
+#
+# (1993-12-05):
+# This material is paraphrased from the 1988 edition of the University of
+# Iceland Almanak.
+#
+# From January 1st, 1908 the whole of Iceland was standardised at 1 hour
+# behind GMT. Previously, local mean solar time was used in different parts
+# of Iceland, the almanak had been based on Reykjavik mean solar time which
+# was 1 hour and 28 minutes behind GMT.
+#
+# "first day of winter" referred to [below] means the first day of the 26 weeks
+# of winter, according to the old icelandic calendar that dates back to the
+# time the norsemen first settled Iceland. The first day of winter is always
+# Saturday, but is not dependent on the Julian or Gregorian calendars.
+#
+# (1993-12-10):
+# I have a reference from the Oxford Icelandic-English dictionary for the
+# beginning of winter, which ties it to the ecclesiastical calendar (and thus
+# to the julian/gregorian calendar) over the period in question.
+# the winter begins on the Saturday next before St. Luke's day
+# (old style), or on St. Luke's day, if a Saturday.
+# St. Luke's day ought to be traceable from ecclesiastical sources. "old style"
+# might be a reference to the Julian calendar as opposed to Gregorian, or it
+# might mean something else (???).
+#
+# From Paul Eggert <eggert@twinsun.com> (1999-10-29):
+# The Iceland Almanak, Shanks and Whitman disagree on many points.
+# We go with the Almanak, except for one claim from Shanks, namely that
+# Reykavik was 21W57 from 1837 to 1908, local mean time before that.

+
+# From Paul Eggert (2001-02-11):
+# A previous version of this database followed Shanks, who writes that
+# Tiraspol switched to Moscow time on 1992-01-19 at 02:00.
+# However, this is most likely an error, as Moldova declared independence
+# on 1991-08-27 (the 1992-01-19 date is that of a Russian decree).
+# In early 1992 there was large-scale interethnic violence in the area
+# and it's possible that some Russophones continued to observe Moscow time.
+# But moldavizolit@tirastel.md and mk@tirastel.md separately reported via
+# Jesper Norgaard that as of 2001-01-24 Tiraspol was like Chisinau.
+# The Tiraspol entry has therefore been removed for now.

+# Netherlands
+
+# Howse writes that the Netherlands' railways used GMT between 1892 and 1940,
+# but for other purposes the Netherlands used Amsterdam mean time.
+
+# However, Robert H. van Gent writes (2001-04-01):
+# Howse's statement is only correct up to 1909. From 1909-05-01 (00:00:00
+# Amsterdam mean time) onwards, the whole of the Netherlands (including
+# the Dutch railways) was required by law to observe Amsterdam mean time
+# (19 minutes 32.13 seconds ahead of GMT). This had already been the
+# common practice (except for the railways) for many decades but it was
+# not until 1909 when the Dutch government finally defined this by law.
+# On 1937-07-01 this was changed to 20 minutes (exactly) ahead of GMT and
+# was generally known as Dutch Time ("Nederlandse Tijd").
+#
+# (2001-04-08):
+# 1892-05-01 was the date when the Dutch railways were by law required to
+# observe GMT while the remainder of the Netherlands adhered to the common
+# practice of following Amsterdam mean time.
+#
+# (2001-04-09):
+# In 1835 the authorities of the province of North Holland requested the
+# municipal authorities of the towns and cities in the province to observe
+# Amsterdam mean time but I do not know in how many cases this request was
+# actually followed.
+#
+# From 1852 onwards the Dutch telegraph offices were by law required to
+# observe Amsterdam mean time. As the time signals from the observatory of
+# Leiden were also distributed by the telegraph system, I assume that most
+# places linked up with the telegraph (and railway) system automatically
+# adopted Amsterdam mean time.
+#
+# Although the early Dutch railway companies initially observed a variety
+# of times, most of them had adopted Amsterdam mean time by 1858 but it
+# was not until 1866 when they were all required by law to observe
+# Amsterdam mean time.
+
+# The data before 1945 are taken from
+# <http://www.phys.uu.nl/~vgent/wettijd/wettijd.htm>.

+# Svalbard & Jan Mayen
+
+# From Steffen Thorsen (2001-05-01):
+# Although I could not find it explicitly, it seems that Jan Mayen and
+# Svalbard have been using the same time as Norway at least since the
+# time they were declared as parts of Norway. Svalbard was declared
+# as a part of Norway by law of 1925-07-17 no 11, section 4 and Jan
+# Mayen by law of 1930-02-27 no 2, section 2. (From
+# http://www.lovdata.no/all/nl-19250717-011.html and
+# http://www.lovdata.no/all/nl-19300227-002.html). The law/regulation
+# for normal/standard time in Norway is from 1894-06-29 no 1 (came
+# into operation on 1895-01-01) and Svalbard/Jan Mayen seem to be a
+# part of this law since 1925/1930. (From
+# http://www.lovdata.no/all/nl-18940629-001.html ) I have not been
+# able to find if Jan Mayen used a different time zone (e.g. -0100)
+# before 1930. Jan Mayen has only been "inhabitated" since 1921 by
+# Norwegian meteorologists and maybe used the same time as Norway ever
+# since 1921. Svalbard (Arctic/Longyearbyen) has been inhabited since
+# before 1895, and therefore probably changed the local time somewhere
+# between 1895 and 1925 (inclusive).
+
+# From Paul Eggert (2001-05-01):
+#
+# Actually, Jan Mayen was never occupied by Germany during World War II,
+# so it must have diverged from Oslo time during the war, as Olso was
+# keeping Berlin time.
+#
+# <http://home.no.net/janmayen/history.htm> says that the meteorologists
+# burned down their station in 1940 and left the island, but returned in
+# 1941 with a small Norwegian garrison and continued operations despite
+# frequent air ttacks from Germans. In 1943 the Americans established a
+# radiolocating station on the island, called "Atlantic City". Possibly
+# the UTC offset changed during the war, but I think it unlikely that
+# Jan Mayen used German daylight-saving rules.
+#
+# Svalbard is more complicated, as it was raided in August 1941 by an
+# Allied party that evacuated the civilian population to England (says
+# <http://www.bartleby.com/65/sv/Svalbard.html>). The Svalbard FAQ
+# <http://www.svalbard.com/SvalbardFAQ.html> says that the Germans were
+# expelled on 1942-05-14. However, small parties of Germans did return,
+# and according to Wilhelm Dege's book "War North of 80" (1954)
+# <http://www.utpress.utoronto.ca/publishing/rights/dege_warnorthof80.htm>
+# the German armed forces at the Svalbard weather station code-named
+# Haudegen did not surrender to the Allies until September 1945.
+#
+# All these events predate our cutoff date of 1970. Unless we can
+# come up with more definitive info about the timekeeping during the
+# war years it's probably best just do do the following for now:

+
+# From Paul Eggert <eggert@twinsun.com> (1999-11-12):
+# Except for Moscow after 1919-07-01, I invented the time zone abbreviations.
+# Moscow time zone abbreviations after 1919-07-01, and Moscow rules after 1991,
+# are from Andrey A. Chernov. The rest is from Shanks, except we follow
+# Chernov's report that 1992 DST transitions were Sat 23:00, not Sun 02:00s.
+#
+# From Stanislaw A. Kuzikowski <S.A.Kuz@iae.nsk.su> (1994-06-29):
+# But now it is some months since Novosibirsk is 3 hours ahead of Moscow!
+# I do not know why they have decided to make this change;
+# as far as I remember it was done exactly during winter->summer switching
+# so we (Novosibirsk) simply did not switch.
+#
+# From Andrey A. Chernov <ache@nagual.ru> (1996-10-04):
+# `MSK' and `MSD' were born and used initially on Moscow computers with
+# UNIX-like OSes by several developer groups (e.g. Demos group, Kiae group)....
+# The next step was the UUCP network, the Relcom predecessor
+# (used mainly for mail), and MSK/MSD was actively used there.
+#
+# From Chris Carrier <72157.3334@CompuServe.COM> (1996-10-30):
+# According to a friend of mine who rode the Trans-Siberian Railroad from
+# Moscow to Irkutsk in 1995, public air and rail transport in Russia ...
+# still follows Moscow time, no matter where in Russia it is located.
+#
+# For Grozny, Chechnya, we have the following story from
+# John Daniszewski, "Scavengers in the Rubble", Los Angeles Times (2001-02-07):
+# News--often false--is spread by word of mouth. A rumor that it was
+# time to move the clocks back put this whole city out of sync with
+# the rest of Russia for two weeks--even soldiers stationed here began
+# enforcing curfew at the wrong time.
+#
+# From Gwillim Law (2001-06-05):
+# There's considerable evidence that Sakhalin Island used to be in
+# UTC+11, and has changed to UTC+10, in this decade. I start with the
+# SSIM, which listed Yuzhno-Sakhalinsk in zone RU10 along with Magadan
+# until February 1997, and then in RU9 with Khabarovsk and Vladivostok
+# since September 1997.... Although the Kuril Islands are
+# administratively part of Sakhalin oblast', they appear to have

+
+# From Ivan Nilsson (2001-04-13), superseding Shanks:
+#
+# The law "Svensk forfattningssamling 1878, no 14" about standard time in 1879:
+# From the beginning of 1879 (that is 01-01 00:00) the time for all
+# places in the country is "the mean solar time for the meridian at
+# three degrees, or twelve minutes of time, to the west of the
+# meridian of the Observatory of Stockholm". The law is dated 1878-05-31.
+#
+# The observatory at that time had the meridian 18 degrees 03' 30"
+# eastern longitude = 01:12:14 in time. Less 12 minutes gives the
+# national standard time as 01:00:14 ahead of GMT....
+#
+# About the beginning of CET in Sweden. The lawtext ("Svensk
+# forfattningssamling 1899, no 44") states, that "from the beginning
+# of 1900... ... the same as the mean solar time for the meridian at
+# the distance of one hour of time from the meridian of the English
+# observatory at Greenwich, or at 12 minutes 14 seconds to the west
+# from the meridian of the Observatory of Stockholm". The law is dated
+# 1899-06-16. In short: At 1900-01-01 00:00:00 the new standard time
+# in Sweden is 01:00:00 ahead of GMT.
+#
+# 1916: The lawtext ("Svensk forfattningssamling 1916, no 124") states
+# that "1916-05-15 is considered to begin one hour earlier". It is
+# pretty obvious that at 05-14 23:00 the clocks are set to 05-15 00:00....
+# Further the law says, that "1916-09-30 is considered to end one hour later".
+#
+# The laws regulating [DST] are available on the site of the Swedish
+# Parliament beginning with 1985 - the laws regulating 1980/1984 are
+# not available on the site (to my knowledge they are only available
+# in Swedish): <http://www.riksdagen.se/english/work/sfst.asp> (type
+# "sommartid" without the quotes in the field "Fritext" and then click
+# the Sok-button).
+#
+# (2001-05-13):
+#
+# I have now found a newspaper stating that at 1916-10-01 01:00
+# summertime the church-clocks etc were set back one hour to show

+# The information from Tom Hofmann is (as far as I know) not entirely correct.
+# After a request from chongo at amdahl I tried to retrieve all information
+# about DST in Europe. I was able to find all from about 1969.
+#
+# ...standardization on DST in Europe started in about 1977 with switches on
+# first Sunday in April and last Sunday in September...
+# In 1981 UK joined Europe insofar that
+# the starting day for both shifted to last Sunday in March. And from 1982
+# the whole of Europe used DST, with switch dates April 1 and October 1 in
+# the Sov[i]et Union. In 1985 the SU reverted to standard Europe[a]n switch
+# dates...
+#
+# It should also be remembered that time-zones are not constants; e.g.
+# Portugal switched in 1976 from MET (or CET) to WET with DST...
+# Note also that though there were rules for switch dates not
+# all countries abided to these dates, and many individual deviations
+# occurred, though not since 1982 I believe. Another note: it is always
+# assumed that DST is 1 hour ahead of normal time, this need not be the
+# case; at least in the Netherlands there have been times when DST was 2 hours

+# Principal of Temple Grove Ladies' Seminary (Saratoga Springs, NY).
+# His pamphlet ``A System of National Time for Railroads'' (1870)
+# was the result of his proposals at the Convention of Railroad Trunk Lines
+# in New York City (1869-10). His 1870 proposal was based on Washington, DC,

+# Daylight Saving Time was first suggested as a joke by Benjamin Franklin
+# in his whimsical essay ``An Economical Project for Diminishing the Cost
+# of Light'' published in the Journal de Paris (1784-04-26).
+# Not everyone is happy with the results:
+#
+# I don't really care how time is reckoned so long as there is some
+# agreement about it, but I object to being told that I am saving
+# daylight when my reason tells me that I am doing nothing of the kind.
+# I even object to the implication that I am wasting something
+# valuable if I stay in bed after the sun has risen. As an admirer
+# of moonlight I resent the bossy insistence of those who want to
+# reduce my time for enjoying it. At the back of the Daylight Saving
+# scheme I detect the bony, blue-fingered hand of Puritanism, eager
+# to push people into bed earlier, and get them up earlier, to make
+# them healthy, wealthy and wise in spite of themselves.

+# Ten years of daylight saving from the Pittsburgh standpoint
+# (Carnegie Library of Pittsburgh, 1927)</a>.
+#
+# Shanks says that DST was called "War Time" in the US in 1918 and 1919.
+# However, DST was imposed by the Standard Time Act of 1918, which
+# was the first nationwide legal time standard, and apparently
+# time was just called "Standard Time" or "Daylight Saving Time".
+
+# From Arthur David Olson:
+# US Daylight Saving Time ended on the last Sunday of *October* in 1974.
+# See, for example, the front page of the Saturday, 1974-10-26
+# and Sunday, 1974-10-27 editions of the Washington Post.
+
+# From Arthur David Olson:
+# Before the Uniform Time Act of 1966 took effect in 1967, observance of
+# Daylight Saving Time in the US was by local option, except during wartime.
+
+# From Arthur David Olson (2000-09-25):
+# Last night I heard part of a rebroadcast of a 1945 Arch Oboler radio drama.
+# In the introduction, Oboler spoke of "Eastern Peace Time."
+# An AltaVista search turned up
+# <a href="http://rowayton.org/rhs/hstaug45.html">:
+# "When the time is announced over the radio now, it is 'Eastern Peace
+# Time' instead of the old familiar 'Eastern War Time.' Peace is wonderful."
+# </a> (August 1945) by way of confirmation.
+
+# From Joseph Gallant <notquite@hotmail.com>, citing
+# George H. Douglas, _The Early Days of Radio Broadcasting_ (1987):
+# At 7 P.M. (Eastern War Time) [on 1945-08-14], the networks were set
+# to switch to London for Attlee's address, but the American people
+# never got to hear his speech live. According to one press account,
+# CBS' Bob Trout was first to announce the word of Japan's surrender,
+# but a few seconds later, NBC, ABC and Mutual also flashed the word
+# of surrender, all of whom interrupting the bells of Big Ben in
+# London which were to precede Mr. Attlee's speech.
+
+# From Paul Eggert (2003-02-09): It was Robert St John, not Bob Trout. From
+# Myrna Oliver's obituary of St John on page B16 of today's Los Angeles Times:
+#
+# ... a war-weary U.S. clung to radios, awaiting word of Japan's surrender.
+# Any announcement from Asia would reach St. John's New York newsroom on a
+# wire service teletype machine, which had prescribed signals for major news.
+# Associated Press, for example, would ring five bells before spewing out
+# typed copy of an important story, and 10 bells for news "of transcendental
+# importance."
+#
+# On Aug. 14, stalling while talking steadily into the NBC networks' open
+# microphone, St. John heard five bells and waited only to hear a sixth bell,
+# before announcing confidently: "Ladies and gentlemen, World War II is over.
+# The Japanese have agreed to our surrender terms."
+#
+# He had scored a 20-second scoop on other broadcasters.

+# Clinton County has joined Wayne County in asking the DoT to change from
+# the Central to the Eastern time zone.... The Wayne County government made
+# the same request in December. And while Russell County officials have not
+# taken action, the majority of respondents to a poll conducted there in
+# August indicated they would like to change to "fast time" also.
+# The three Lake Cumberland counties are the farthest east of any U.S.
+# location in the Central time zone.
+#
+# From Rich Wales (2000-08-29):
+# After prolonged debate, and despite continuing deep differences of opinion,
+# Wayne County (central Kentucky) is switching from Central (-0600) to Eastern
+# (-0500) time. They won't "fall back" this year. See Sara Shipley,

+# erect a sundial in front of the city hall was referred to the
+# Committee on Sewers. Then, in 1905, Central time was adopted

+#
+# This story is too entertaining to be false, so go with Howse over Shanks.

+# They also write that Quebec east of the -63 meridian is supposed to

+
+# From Mark Brader (2003-07-26):
+# The first actual adoption of DST in Canada was at the municipal
+# level. As the [Toronto] Star put it (1912-06-07), "While people
+# elsewhere have long been talking of legislation to save daylight,
+# the city of Moose Jaw [Saskatchewan] has acted on its own hook."
+# DST in Moose Jaw began on Saturday, 1912-06-01 (no time mentioned:
+# presumably late evening, as below), and would run until "the end of
+# the summer". The discrepancy between municipal time and railroad
+# time was noted.
+
+# From Paul Eggert (2003-07-27):
+# Willett (1914-03) notes that DST "has been in operation ... in the
+# City of Moose Jaw, Saskatchewan, for one year."
+
+# From Paul Eggert (2000-10-02):
+# Shanks writes that since 1970 most of this region has been like Regina.
+# Some western towns (e.g. Swift Current) switched from MST/MDT to CST in 1972.
+# Other western towns (e.g. Lloydminster) are like Edmonton.
+# Matthews and Vincent (1998) write that Denare Beach and Creighton
+# are like Winnipeg, in violation of Saskatchewan law.
+
+# From W. Jones <jones@skdad.usask.ca> (1992-11-06):
+# The. . .below is based on information I got from our law library, the
+# provincial archives, and the provincial Community Services department.
+# A precise history would require digging through newspaper archives, and
+# since you didn't say what you wanted, I didn't bother.
+#
+# Saskatchewan is split by a time zone meridian (105W) and over the years
+# the boundary became pretty ragged as communities near it reevaluated
+# their affiliations in one direction or the other. In 1965 a provincial
+# referendum favoured legislating common time practices.
+#
+# On 15 April 1966 the Time Act (c. T-14, Revised Statutes of
+# Saskatchewan 1978) was proclaimed, and established that the eastern
+# part of Saskatchewan would use CST year round, that districts in
+# northwest Saskatchewan would by default follow CST but could opt to
+# follow Mountain Time rules (thus 1 hour difference in the winter and
+# zero in the summer), and that districts in southwest Saskatchewan would
+# by default follow MT but could opt to follow CST.
+#
+# It took a few years for the dust to settle (I know one story of a town
+# on one time zone having its school in another, such that a mom had to
+# serve her family lunch in two shifts), but presently it seems that only
+# a few towns on the border with Alberta (e.g. Lloydminster) follow MT
+# rules any more; all other districts appear to have used CST year round

+# Mexico
+
+# From Paul Eggert (2001-03-05):
+# The Investigation and Analysis Service of the
+# Mexican Library of Congress (MLoC) has published a
+# <a href="http://www.cddhcu.gob.mx/bibliot/publica/inveyana/polisoc/horver/">
+# history of Mexican local time (in Spanish)
+# </a>.
+#
+# Here are the discrepancies between Shanks and the MLoC.
+# (In all cases we go with the MLoC.)
+# Shanks reports that Baja was at -8:00 in 1922/1923.
+# Shanks says the 1930 transition in Baja was 1930-11-16.
+# Shanks reports no DST during summer 1931.
+# Shanks reports a transition at 1032-03-30 23:00, not 1932-04-01.
+# Shanks does not report transitions for Baja in 1945 or 1948.
+# Shanks reports southern Mexico transitions on 1981-12-01, not 12-23.
+# Shanks says Quintana Roo switched to -6:00 on 1982-12-02, and to -5:00
+# on 1997-10-26 at 02:00.
+
+# From Gwillim Law (2001-02-20):
+# There are some other discrepancies between the Decrees page and the
+# tz database. I think they can best be explained by supposing that
+# the researchers who prepared the Decrees page failed to find some of
+# the relevant documents.
+
+# From Paul Eggert (2000-07-26):
+# Shanks gives 1942-04-01 instead of 1942-04-24, and omits the 1981
+# and 1988 DST experiments. Go with spin.com.mx.
+
+# From Alan Perry <alan.perry@eng.sun.com> (1996-02-15):
+# A guy from our Mexico subsidiary finally found the Presidential Decree
+# outlining the timezone changes in Mexico.
+#
+# ------------- Begin Forwarded Message -------------
+#
+# I finally got my hands on the Official Presidential Decree that sets up the
+# rules for the DST changes. The rules are:
+#
+# 1. The country is divided in 3 timezones:
+# - Baja California Norte (the Mexico/BajaNorte TZ)
+# - Baja California Sur, Nayarit, Sinaloa and Sonora (the Mexico/BajaSur TZ)
+# - The rest of the country (the Mexico/General TZ)
+#
+# 2. From the first Sunday in April at 2:00 AM to the last Sunday in October
+# at 2:00 AM, the times in each zone are as follows:
+# BajaNorte: GMT+7
+# BajaSur: GMT+6
+# General: GMT+5
+#
+# 3. The rest of the year, the times are as follows:
+# BajaNorte: GMT+8
+# BajaSur: GMT+7
+# General: GMT+6
+#
+# The Decree was published in Mexico's Official Newspaper on January 4th.
+#
+# -------------- End Forwarded Message --------------
+# From Paul Eggert (1996-06-12):
+# For an English translation of the decree, see
+# <a href="http://mexico-travel.com/extra/timezone_eng.html">
+# ``Diario Oficial: Time Zone Changeover'' (1996-01-04).
+# </a>
+
+# From Rives McDow (1998-10-08):
+# The State of Quintana Roo has reverted back to central STD and DST times
+# (i.e. UTC -0600 and -0500 as of 1998-08-02).
+
+# From Rives McDow (2000-01-10):
+# Effective April 4, 1999 at 2:00 AM local time, Sonora changed to the time
+# zone 5 hours from the International Date Line, and will not observe daylight
+# savings time so as to stay on the same time zone as the southern part of
+# Arizona year round.
+
+# From Jesper Norgaard, translating
+# <http://www.reforma.com/nacional/articulo/064327/> (2001-01-17):
+# In Oaxaca, the 55.000 teachers from the Section 22 of the National
+# Syndicate of Education Workers, refuse to apply daylight saving each
+# year, so that the more than 10,000 schools work at normal hour the
+# whole year.
+
+# From Gwillim Law (2001-01-19):
+# <http://www.reforma.com/negocios_y_dinero/articulo/064481/> ... says
+# (translated):...
+# January 17, 2000 - The Energy Secretary, Ernesto Martens, announced

+# [translated], says "summer time will ... take effect on the first Sunday
+# in May, and end on the last Sunday of September.
+
+# From Arthur David Olson (2001-01-25):
+# The 2001-01-24 traditional Washington Post contained the page one
+# story "Timely Issue Divides Mexicans."...
+# http://www.washingtonpost.com/wp-dyn/articles/A37383-2001Jan23.html
+# ... Mexico City Mayor Lopez Obrador "...is threatening to keep
+# Mexico City and its 20 million residents on a different time than
+# the rest of the country..." In particular, Lopez Obrador would abolish
+# observation of Daylight Saving Time.
+
+# <a href="http://www.conae.gob.mx/ahorro/decretohorver2001.html#decre">
+# Official statute published by the Energy Department
+# </a> (2001-02-01) shows Baja and Chihauhua as still using US DST rules,
+# and Sonora with no DST. This was reported by Jesper Norgaard (2001-02-03).
+
+# From Paul Eggert (2001-03-03):
+#
+# <a href="http://www.latimes.com/news/nation/20010303/t000018766.html">
+# James F. Smith writes in today's LA Times
+# </a>
+# * Sonora will continue to observe standard time.
+# * Last week Mexico City's mayor Andres Manuel Lopez Obrador decreed that
+# the Federal District will not adopt DST.
+# * 4 of 16 district leaders announced they'll ignore the decree.
+# * The decree does not affect federal-controlled facilities including
+# the airport, banks, hospitals, and schools.
+#
+# For now we'll assume that the Federal District will bow to federal rules.
+
+# From Jesper Norgaard (2001-04-01):
+# I found some references to the Mexican application of daylight
+# saving, which modifies what I had already sent you, stating earlier
+# that a number of northern Mexican states would go on daylight
+# saving. The modification reverts this to only cover Baja California
+# (Norte), while all other states (except Sonora, who has no daylight
+# saving all year) will follow the original decree of president
+# Vicente Fox, starting daylight saving May 6, 2001 and ending
+# September 30, 2001.

+
+# From Reuters (2001-09-04):
+# Mexico's Supreme Court on Tuesday declared that daylight savings was
+# unconstitutional in Mexico City, creating the possibility the
+# capital will be in a different time zone from the rest of the nation
+# next year.... The Supreme Court's ruling takes effect at 2:00
+# a.m. (0800 GMT) on Sept. 30, when Mexico is scheduled to revert to
+# standard time. "This is so residents of the Federal District are not
+# subject to unexpected time changes," a statement from the court said.
+
+# From Jesper Norgaard Welen (2002-03-12):
+# ... consulting my local grocery store(!) and my coworkers, they all insisted
+# that a new decision had been made to reinstate US style DST in Mexico....
+# http://www.conae.gob.mx/ahorro/horaver2001_m1_2002.html (2002-02-20)
+# confirms this. Sonora as usual is the only state where DST is not applied.

+# From Paul Eggert (2001-03-05):
+# Formerly there was an America/Ensenada zone, which differed from
+# America/Tijuana only in that it did not observe DST from 1976
+# through 1995. This was as per Shanks. However, Guy Harris reports
+# that the 1987 OAG says "Only Ensenada, Mexicale, San Felipe and
+# Tijuana observe DST," which contradicts Shanks but does imply that
+# DST-observance was a town-by-town matter back then. This concerns
+# data after 1970 so most likely there should be at least one Zone
+# other than America/Tijuana for Baja, but it's not clear yet what its
+# name or contents should be.

+# That URL (2000-10-26, in Spanish) says they planned to use US-style DST.
+
+# From Rives McDow (2000-12-01):
+# Dominican Republic changed its mind and presidential decree on Tuesday,
+# November 28, 2000, with a new decree. On Sunday, December 3 at 1:00 AM the
+# Dominican Republic will be reverting to 8 hours from the International Date
+# Line, and will not be using DST in the foreseeable future. The reason they
+# decided to use DST was to be in synch with Puerto Rico, who was also going
+# to implement DST. When Puerto Rico didn't implement DST, the president
+# decided to revert.

+# Apparent noon times below are for Riyadh; they're a bit off for other places.
+# Times were computed using a formula provided by the U. S. Naval Observatory:
+# eqt = -105.8 * sin(l) + 596.2 * sin(2 * l) + 4.4 * sin(3 * l)
+# -12.7 * sin(4 * l) - 429.0 * cos(l) - 2.1 * cos (2 * l)
+# + 19.3 * cos(3 * l);
+# where l is the "mean longitude of the Sun" given by
+# l = 279.642 degrees + 0.985647 * d
+# and d is the interval in days from January 0, 0 hours Universal Time
+# (equaling the day of the year plus the fraction of a day from zero hours).
+# The accuracy of the formula is plus or minus three seconds.
+#
+# Rounding to the nearest five seconds results in fewer than
+# 256 different "time types"--a limit that's faced because time types are
+# stored on disk as unsigned chars.

+# San Diego: ACS Publications, Inc. (1999).
+#
+# Gwillim Law writes that a good source

+# Association's Standard Schedules Information Manual (IATA SSIM),

+# of the IATA's data after 1990.
+#
+# Except where otherwise noted, Shanks is the source for entries through 1990,
+# and IATA SSIM is the source for entries after 1990.
+#
+# Earlier editions of these tables used the North American style (e.g. ARST and
+# ARDT for Argentine Standard and Daylight Time), but the following quote
+# suggests that it's better to use European style (e.g. ART and ARST).
+# I suggest the use of _Summer time_ instead of the more cumbersome
+# _daylight-saving time_. _Summer time_ seems to be in general use
+# in Europe and South America.
+# -- E O Cutler, _New York Times_ (1937-02-14), quoted in
+# H L Mencken, _The American Language: Supplement I_ (1960), p 466
+#
+# Earlier editions of these tables also used the North American style
+# for time zones in Brazil, but this was incorrect, as Brazilians say
+# "summer time". Reinaldo Goulart, a Sao Paulo businessman active in
+# the railroad sector, writes (1999-07-06):
+# The subject of time zones is currently a matter of discussion/debate in
+# Brazil. Let's say that "the Brasilia time" is considered the
+# "official time" because Brasilia is the capital city.
+# The other three time zones are called "Brasilia time "minus one" or
+# "plus one" or "plus two". As far as I know there is no such
+# name/designation as "Eastern Time" or "Central Time".
+# So I invented the following (English-language) abbreviations for now.

+
+# From Paul Eggert <eggert@twinsun.com> (1993-11-18):
+# The mayor of Rio recently attempted to change the time zone rules
+# just in his city, in order to leave more summer time for the tourist trade.
+# The rule change lasted only part of the day;
+# the federal government refused to follow the city's rules, and business
+# was in a chaos, so the mayor backed down that afternoon.
+
+# From IATA SSIM (1996-02):
+# _Only_ the following states in BR1 observe DST: Rio Grande do Sul (RS),
+# Santa Catarina (SC), Parana (PR), Sao Paulo (SP), Rio de Janeiro (RJ),
+# Espirito Santo (ES), Minas Gerais (MG), Bahia (BA), Goias (GO),
+# Distrito Federal (DF), Tocantins (TO), Sergipe [SE] and Alagoas [AL].
+# [The last three states are new to this issue of the IATA SSIM.]
+
+# From Gwillim Law (1996-10-07):
+# Geography, history (Tocantins was part of Goias until 1989), and other
+# sources of time zone information lead me to believe that AL, SE, and TO were
+# always in BR1, and so the only change was whether or not they observed DST....
+# The earliest issue of the SSIM I have is 2/91. Each issue from then until
+# 9/95 says that DST is observed only in the ten states I quoted from 9/95,
+# along with Mato Grosso (MT) and Mato Grosso do Sul (MS), which are in BR2
+# (UTC-4).... The other two time zones given for Brazil are BR3, which is
+# UTC-5, no DST, and applies only in the state of Acre (AC); and BR4, which is
+# UTC-2, and applies to Fernando de Noronha (formerly FN, but I believe it's
+# become part of the state of Pernambuco). The boundary between BR1 and BR2
+# has never been clearly stated. They've simply been called East and West.
+# However, some conclusions can be drawn from another IATA manual: the Airline
+# Coding Directory, which lists close to 400 airports in Brazil. For each
+# airport it gives a time zone which is coded to the SSIM. From that
+# information, I'm led to conclude that the states of Amapa (AP), Ceara (CE),
+# Maranhao (MA), Paraiba (PR), Pernambuco (PE), Piaui (PI), and Rio Grande do
+# Norte (RN), and the eastern part of Para (PA) are all in BR1 without DST.
+
+# From Marcos Tadeu (1998-09-27):
+# <a href="http://pcdsh01.on.br/verao1.html">
+# Brazilian official page
+# </a>
+
+# From Jesper Norgaard (2000-11-03):
+# [For an official list of which regions in Brazil use which time zones, see:]
+# http://pcdsh01.on.br/Fusbr.htm
+# http://pcdsh01.on.br/Fusbrhv.htm
+
+# From Celso Doria via David Madeo (2002-10-09):
+# The reason for the delay this year has to do with elections in Brazil.
+#
+# Unlike in the United States, elections in Brazil are 100% computerized and
+# the results are known almost immediately. Yesterday, it was the first
+# round of the elections when 115 million Brazilians voted for President,
+# Governor, Senators, Federal Deputies, and State Deputies. Nobody is
+# counting (or re-counting) votes anymore and we know there will be a second
+# round for the Presidency and also for some Governors. The 2nd round will
+# take place on October 27th.
+#
+# The reason why the DST will only begin November 3rd is that the thousands
+# of electoral machines used cannot have their time changed, and since the
+# Constitution says the elections must begin at 8:00 AM and end at 5:00 PM,
+# the Government decided to postpone DST, instead of changing the Constitution
+# (maybe, for the next elections, it will be possible to change the clock)...

+
+# From Eduardo Krell (1995-10-19):
+# The law says to switch to DST at midnight [24:00] on the second SATURDAY
+# of October.... The law is the same for March and October.
+# (1998-09-29):
+# Because of the drought this year, the government decided to go into
+# DST earlier (saturday 9/26 at 24:00). This is a one-time change only ...
+# (unless there's another dry season next year, I guess).
+
+# From Julio I. Pacheco Troncoso (1999-03-18):
+# Because of the same drought, the government decided to end DST later,
+# on April 3, (one-time change).
+
+# From Gwillim Law (2001-05-04):
+# I came across another article in "La Tercera" about Chilean DST.
+# <http://www.tercera.cl/diario/2000/10/13/t-extras.html>
+# It clearly confirms my earlier suggestion, that DST begins at 22:00
+# on Easter Island.... But it also seems to be saying that the
+# observance of DST in Chile began in 1966, rather than 1969 as
+# ... [Shanks] has it....
+#
+# My translation:
+#
+# "The Chilean Army has announced that summer time will begin tomorrow,
+# Saturday, October 14 in continental Chile, insular Chile, and
+# Antarctica, as provided by Supreme Decree 25 of January 11, 1966.
+# By the preceding, official time in continental Chile and Chilean
+# Antarctic, and official time in Western Insular Chile, which applies
+# to Easter Island and Sala y Gomez Island, will be set forward at
+# midnight and at 22:00, respectively, by 20 minutes."
+
+# From Paul Eggert (2001-05-04):
+# Go with this article in preference to Shanks's 1969 date for modern DST.
+# Assume this rule has been used since DST was introduced in the islands.
+
+# From Paul Eggert (2002-10-24):
+# <http://www.shoa.cl/shoa/faqhoraoficial.htm> gives many details that
+# disagree with the following table, but we haven't had time to compare them.

+
+# From Rives McDow (2001-02-13):
+#
+# I have communicated several times with people there, and the last
+# time I had communications that was helpful was in 1998. Here is
+# what was said then:
+#
+# "The general rule was that Stanley used daylight saving and the Camp
+# did not. However for various reasons many people in the Camp have
+# started to use daylight saving (known locally as 'Stanley Time')
+# There is no rule as to who uses daylight saving - it is a matter of
+# personal choice and so it is impossible to draw a map showing who
+# uses it and who does not. Any list would be out of date as soon as
+# it was produced. This year daylight saving ended on April 18/19th
+# and started again on September 12/13th. I do not know what the rule
+# is, but can find out if you like. We do not change at the same time
+# as UK or Chile."
+#
+# I did have in my notes that the rule was "Second Saturday in Sep at
+# 0:00 until third Saturday in Apr at 0:00". I think that this does
+# not agree in some cases with Shanks; is this true?
+#
+# Also, there is no mention in the list that some areas in the
+# Falklands do not use DST. I have found in my communications there
+# that these areas are on the western half of East Falkland and all of
+# West Falkland. Stanley is the only place that consistently observes
+# DST. Again, as in other places in the world, the farmers don't like
+# it. West Falkland is almost entirely sheep farmers.
+#
+# I know one lady there that keeps a list of which farm keeps DST and
+# which doesn't each year. She runs a shop in Stanley, and says that
+# the list changes each year. She uses it to communicate to her
+# customers, catching them when they are home for lunch or dinner.
+
+# From Paul Eggert (2001-03-05):
+# For now, we'll just record the time in Stanley, since we have no
+# better info.

+# TZ zone descriptions
+#
+# From Paul Eggert <eggert@twinsun.com> (1996-08-05):
+#
+# This file contains a table with the following columns:
+# 1. ISO 3166 2-character country code. See the file `iso3166.tab'.
+# 2. Latitude and longitude of the zone's principal location
+# in ISO 6709 sign-degrees-minutes-seconds format,
+# either +-DDMM+-DDDMM or +-DDMMSS+-DDDMMSS,
+# first latitude (+ is north), then longitude (+ is east).
+# 3. Zone name used in value of TZ environment variable.
+# 4. Comments; present if and only if the country has multiple rows.
+#
+# Columns are separated by a single tab.
+# The table is sorted first by country, then an order within the country that
+# (1) makes some geographical sense, and
+# (2) puts the most populous zones first, where that does not contradict (1).
+#
+# Lines beginning with `#' are comments.
