From 7cce222c965dec93327692dbac9c340a6220afe9 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sat, 25 Nov 2017 15:30:11 -0500 Subject: [PATCH] Replace raw timezone source data with IANA's new compact format. Traditionally IANA has distributed their timezone data in pure source form, replete with extensive historical comments. As of release 2017c, they've added a compact single-file format that omits comments and abbreviates command keywords. This form is way shorter than the pure source, even before considering its allegedly better compressibility. Hence, let's distribute the data in that form rather than pure source. I'm pushing this now, rather than at the next timezone database update, so that it's easy to confirm that this data file produces compiled zic output that's identical to what we were getting before.

This caught on -# at first only in coastal areas observing UT+8. -# * During WWII all of China was in theory was at UT+7. In practice -# this was ignored in the west, and I presume was ignored in -# Japanese-occupied territory. -# * Japanese-occupied Manchuria was at UT+9, i.e., Japan time. -# * The five-zone plan was resurrected after WWII and officially put into -# place (with some modifications) in March 1948. It's not clear -# how well it was observed in areas under Nationalist control. -# * The People's Liberation Army used UT+8 during the civil war. -# -# An AP article "Shanghai Internat'l Area Little Changed" in the -# Lewiston (ME) Daily Sun (1939-05-29), p 17, said "Even the time is -# different - the occupied districts going by Tokyo time, an hour -# ahead of that prevailing in the rest of Shanghai."

The government of the Xinjiang -# Uyghur Autonomous Region, (XAUR, or just Xinjiang for short) as well as -# local governments such as the Ürümqi city government use both times in -# publications, referring to what is popularly called Xinjiang time as -# "Ürümqi time." When Uyghurs make an appointment in the Uyghur language -# they almost invariably use Xinjiang time. -# -# (Their ethnic Han compatriots would typically have no clue of its -# widespread use, however, because so extremely few of them are fluent in -# Uyghur, comparable to the number of Anglo-Americans fluent in Navajo.) -# -# (...As with the rest of China there was a brief interval ending in 1990 -# or 1991 when summer time was in use. The confusion was severe, with -# the province not having dual times but four times in use at the same -# time. Some areas remained on standard Xinjiang time or Beijing time and -# others moving their clocks ahead.) - -# From Luther Ma (2009-11-19): -# With the risk of being redundant to previous answers these are the most common -# English "transliterations" (w/o using non-English symbols): -# -# 1.

Likewise for Kashgar and the rest of south Xinjiang I don't know of any -# start date for Xinjiang time. -# -# Without having access to local historical records, nor the ability to legally -# publish them, I would go with October 1, 1949, when Xinjiang became the Uyghur -# Autonomous Region under the PRC. (Before that Uyghurs, of course, would also -# not be using Beijing time, but some local time.) - -# From David Cochrane (2014-03-26): -# Just a confirmation that Ürümqi time was implemented in Ürümqi on 1 Feb 1986: -# https://content.time.com/time/magazine/article/0,9171,960684,00.html - -# From Luther Ma (2014-04-22): -# I have interviewed numerous people of various nationalities and from -# different localities in Xinjiang and can confirm the information in Guo's -# report regarding Xinjiang, as well as the Time article reference by David -# Cochrane. Whether officially recognized or not (and both are officially -# recognized), two separate times have been in use in Xinjiang since at least -# the Cultural Revolution: Xinjiang Time (XJT), aka Ürümqi Time or local time; -# and Beijing Time. There is no confusion in Xinjiang as to which name refers -# to which time. Both are widely used in the province, although in some -# population groups might be use one to the exclusion of the other. The only -# problem is that computers and smart phones list Ürümqi (or Kashgar) as -# having the same time as Beijing. - -# From Paul Eggert (2014-06-30): -# In the early days of the PRC, Tibet was given its own time zone (UT +06) -# but this was withdrawn in 1959 and never reinstated; see Tubten Khétsun, -# Memories of life in Lhasa under Chinese Rule, Columbia U Press, ISBN -# 978-0231142861 (2008), translator's introduction by Matthew Akester, p x. -# As this is before our 1970 cutoff, Tibet doesn't need a separate zone. -# -# Xinjiang Time is well-documented as being officially recognized. E.g., see -# "The Working-Calendar for The Xinjiang Uygur Autonomous Region Government" -# (2014-04-22). -# Unfortunately, we have no good records of time in Xinjiang before 1986. -# During the 20th century parts of Xinjiang were ruled by the Qing dynasty, -# the Republic of China, various warlords, the First and Second East Turkestan -# Republics, the Soviet Union, the Kuomintang, and the People's Republic of -# China, and tracking down all these organizations' timekeeping rules would be -# quite a trick.

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 Paul Eggert (2014-06-30): -# -# Inspired by Mackin's remarks quoted above, earlier versions of this -# file used "EST" for both Eastern Standard Time and Eastern Summer -# Time in Australia, and similarly for "CST", "CWST", and "WST". -# However, these abbreviations were confusing and were not common -# practice among Australians, and there were justifiable complaints -# about them, so I attempted to survey current Australian usage. -# For the tz database, the full English phrase is not that important; -# what matters is the abbreviation. It's difficult to survey the web -# directly for abbreviation usage, as there are so many false hits for -# strings like "EST" and "EDT", so I looked for pages that defined an -# abbreviation for eastern or central DST in Australia, and got the -# following numbers of unique hits for the listed Google queries: -# -# 10 "Eastern Daylight Time AEST" site:au [some are false hits] -# 10 "Eastern Summer Time AEST" site:au -# 10 "Summer Time AEDT" site:au -# 13 "EDST Eastern Daylight Saving Time" site:au -# 18 "Summer Time ESST" site:au -# 28 "Eastern Daylight Saving Time EDST" site:au -# 39 "EDT Eastern Daylight Time" site:au [some are false hits] -# 53 "Eastern Daylight Time EDT" site:au [some are false hits] -# 54 "AEDT Australian Eastern Daylight Time" site:au -# 182 "Eastern Daylight Time AEDT" site:au -# -# 17 "Central Daylight Time CDT" site:au [some are false hits] -# 46 "Central Daylight Time ACDT" site:au -# -# I tried several other variants (e.g., "Eastern Summer Time EST") but -# they all returned fewer than 10 unique hits. I also looked for pages -# mentioning both "western standard time" and an abbreviation, since -# there is no WST in the US to generate false hits, and found: -# -# 156 "western standard time" AWST site:au -# 226 "western standard time" WST site:au -# -# I then surveyed the top ten newspapers in Australia by circulation as -# listed in Wikipedia, using Google queries like "AEDT site:heraldsun.com.au" -# and obtaining estimated counts from the initial page of search results. -# All ten papers greatly preferred "AEDT" to "EDT". The papers -# surveyed were the Herald Sun, The Daily Telegraph, The Courier-Mail, -# The Sydney Morning Herald, The West Australian, The Age, The Advertiser, -# The Australian, The Financial Review, and The Herald (Newcastle). -# -# I also searched for historical usage, to see whether abbreviations -# like "AEDT" are new. A Trove search -# found only one newspaper (The Canberra Times) with a house style -# dating back to the 1970s, I expect because other newspapers weren't -# fully indexed. The Canberra Times strongly preferred abbreviations -# like "AEDT". The first occurrence of "AEDT" was a World Weather -# column (1971-11-17, page 24), and of "ACDT" was a Scoreboard column -# (1993-01-24, p 16). The style was the typical usage but was not -# strictly enforced; for example, "Welcome to the twilight zones ..." -# (1994-10-29, p 1) uses the abbreviations AEST/AEDT, CST/CDT, and -# WST, and goes on to say, "The confusion and frustration some feel -# about the lack of uniformity among Australia's six states and two -# territories has prompted one group to form its very own political -# party -- the Sydney-based Daylight Saving Extension Party." -# -# I also surveyed federal government sources. They did not agree: -# -# The Australian Government (2014-03-26) -# http://australia.gov.au/about-australia/our-country/time -# (This document was produced by the Department of Finance.) -# AEST ACST AWST AEDT ACDT -# -# Bureau of Meteorology (2012-11-08) -# http://www.bom.gov.au/climate/averages/tables/daysavtm.shtml -# EST CST WST EDT CDT -# -# Civil Aviation Safety Authority (undated) -# http://services.casa.gov.au/outnback/inc/pages/episode3/episode-3_time_zones.shtml -# EST CST WST (no abbreviations given for DST) -# -# Geoscience Australia (2011-11-24) -# http://www.ga.gov.au/geodesy/astro/sunrise.jsp -# AEST ACST AWST AEDT ACDT -# -# Parliamentary Library (2008-11-10) -# https://www.aph.gov.au/binaries/library/pubs/rp/2008-09/09rp14.pdf -# EST CST WST preferred for standard time; AEST AEDT ACST ACDT also used -# -# The Transport Safety Bureau has an extensive series of accident reports, -# and investigators seem to use whatever abbreviation they like. -# Googling site:atsb.gov.au found the following number of unique hits: -# 311 "ESuT", 195 "EDT", 26 "AEDT", 83 "CSuT", 46 "CDT". -# "_SuT" tended to appear in older reports, and "A_DT" tended to -# appear in reports of events with international implications. -# -# From the above it appears that there is a working consensus in -# Australia to use trailing "DT" for daylight saving time; although -# some sources use trailing "SST" or "ST" or "SuT" they are by far in -# the minority. The case for leading "A" is weaker, but since it -# seems to be preferred in the overall web and is preferred in all -# the leading newspaper websites and in many government departments, -# it has a stronger case than omitting the leading "A". The current -# version of the database therefore uses abbreviations like "AEST" and -# "AEDT" for Australian time zones. - -# From Paul Eggert (1995-12-19): -# Shanks & Pottenger report 2:00 for all autumn changes in Australia and NZ. -# Mark Prior 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. - -# From Eric Ulevik (1998-01-05): -# -# Here are some URLs to Australian time legislation.

They used to be 1/2 hour different from us here in -# Sacramento but it was changed a couple of years ago. - - -# (Western) Samoa and American Samoa - -# Howse writes (p 153) that after the 1879 standardization on Antipodean -# time by the British governor of Fiji, the King of Samoa decided to change -# "the date in his kingdom from the Antipodean to the American system, -# ordaining - by a masterpiece of diplomatic flattery - that -# the Fourth of July should be celebrated twice in that year." -# This happened in 1892, according to the Evening News (Sydney) of 1892-07-20. -# https://www.staff.science.uu.nl/~gent0113/idl/idl.htm - -# Although Shanks & Pottenger says they both switched to UT -11:30 -# in 1911, and to -11 in 1950. many earlier sources give -11 -# for American Samoa, e.g., the US National Bureau of Standards -# circular "Standard Time Throughout the World", 1932. -# Assume American Samoa switched to -11 in 1911, not 1950, -# and that after 1950 they agreed until (western) Samoa skipped a -# day in 2011.

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 Tāufaʻāhau Tupou IV, then Crown Prince -# Tungī, 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?" -# -# The Crown Prince, presented an unanswerable argument: "Remember that -# on the World Day of Prayer, you would be the first people on Earth -# to say your prayers in the morning." - -# From Paul Eggert (2006-03-22): -# Shanks & Pottenger say the transition was on 1968-10-01; go with Mundell. - -# From Eric Ulevik (1999-05-03): -# Tonga's director of tourism, who is also secretary of the National Millennium -# Committee, has a plan to get Tonga back in front. -# He has proposed a one-off move to tropical daylight saving for Tonga from -# October to March, which has won approval in principle from the Tongan -# Government. - -# From Steffen Thorsen (1999-09-09): -# * Tonga will introduce DST in November -# -# I was given this link by John Letts: -# http://news.bbc.co.uk/hi/english/world/asia-pacific/newsid_424000/424764.stm -# -# I have not been able to find exact dates for the transition in November -# yet.

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.... 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. - -# From Wikipedia (2005-08-31): -# Before 1920, all ships kept local apparent time on the high seas by setting -# their clocks at night or at the morning sight so that, given the ship's -# speed and direction, it would be 12 o'clock when the Sun crossed the ship's -# meridian (12 o'clock = local apparent noon). During 1917, at the -# Anglo-French Conference on Time-keeping at Sea, it was recommended that all -# ships, both military and civilian, should adopt hourly standard time zones -# on the high seas. Whenever a ship was within the territorial waters of any -# nation it would use that nation's standard time. The captain was permitted -# to change his ship's clocks at a time of his choice following his ship's -# entry into another zone time - he often chose midnight. These zones were -# adopted by all major fleets between 1920 and 1925 but not by many -# independent merchant ships until World War II. - -# From Paul Eggert, using references suggested by Oscar van Vlijmen -# (2005-03-20): -# -# The American Practical Navigator (2002) -# http://pollux.nss.nima.mil/pubs/pubs_j_apn_sections.html?rid=187 -# talks only about the 180-degree meridian with respect to ships in -# international waters; it ignores the international date line. diff --git a/src/timezone/data/backward b/src/timezone/data/backward deleted file mode 100644 index 2141f0d579..0000000000 --- a/src/timezone/data/backward +++ /dev/null @@ -1,128 +0,0 @@ -# This file is in the public domain, so clarified as of -# 2009-05-17 by Arthur David Olson. - -# This file provides links between current names for time zones -# and their old names.

The Ordnance Survey grid reference is TQ172761. -# -# [This yields GMTOFF = -0:01:15 for London LMT in the 18th century.] - -# From Paul Eggert (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 (2014-07-19): -# The ancients had no need for daylight saving, as they kept time -# informally or via hours whose length depended on the time of year. -# Daylight saving time in its modern sense was invented by the -# New Zealand entomologist George Vernon Hudson (1867-1946), -# whose day job as a postal clerk led him to value -# after-hours daylight in which to pursue his research. -# In 1895 he presented a paper to the Wellington Philosophical Society -# that proposed a two-hour daylight-saving shift.

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 entries before 1945 are taken from -# https://www.staff.science.uu.nl/~gent0113/wettijd/wettijd.htm - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Neth 1916 only - May 1 0:00 1:00 NST # Netherlands Summer Time -Rule Neth 1916 only - Oct 1 0:00 0 AMT # Amsterdam Mean Time -Rule Neth 1917 only - Apr 16 2:00s 1:00 NST -Rule Neth 1917 only - Sep 17 2:00s 0 AMT -Rule Neth 1918 1921 - Apr Mon>=1 2:00s 1:00 NST -Rule Neth 1918 1921 - Sep lastMon 2:00s 0 AMT -Rule Neth 1922 only - Mar lastSun 2:00s 1:00 NST -Rule Neth 1922 1936 - Oct Sun>=2 2:00s 0 AMT -Rule Neth 1923 only - Jun Fri>=1 2:00s 1:00 NST -Rule Neth 1924 only - Mar lastSun 2:00s 1:00 NST -Rule Neth 1925 only - Jun Fri>=1 2:00s 1:00 NST -# From 1926 through 1939 DST began 05-15, except that it was delayed by a week -# in years when 05-15 fell in the Pentecost weekend. -Rule Neth 1926 1931 - May 15 2:00s 1:00 NST -Rule Neth 1932 only - May 22 2:00s 1:00 NST -Rule Neth 1933 1936 - May 15 2:00s 1:00 NST -Rule Neth 1937 only - May 22 2:00s 1:00 NST -Rule Neth 1937 only - Jul 1 0:00 1:00 S -Rule Neth 1937 1939 - Oct Sun>=2 2:00s 0 - -Rule Neth 1938 1939 - May 15 2:00s 1:00 S -Rule Neth 1945 only - Apr 2 2:00s 1:00 S -Rule Neth 1945 only - Sep 16 2:00s 0 - -# -# Amsterdam Mean Time was +00:19:32.13 exactly, but the .13 is omitted -# below because the current format requires GMTOFF to be an integer. -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Europe/Amsterdam 0:19:32 - LMT 1835 - 0:19:32 Neth %s 1937 Jul 1 - 0:20 Neth +0020/+0120 1940 May 16 0:00 - 1:00 C-Eur CE%sT 1945 Apr 2 2:00 - 1:00 Neth CE%sT 1977 - 1:00 EU CE%sT - -# Norway -# http://met.no/met/met_lex/q_u/sommertid.html (2004-01) agrees with Shanks & -# Pottenger. -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Norway 1916 only - May 22 1:00 1:00 S -Rule Norway 1916 only - Sep 30 0:00 0 - -Rule Norway 1945 only - Apr 2 2:00s 1:00 S -Rule Norway 1945 only - Oct 1 2:00s 0 - -Rule Norway 1959 1964 - Mar Sun>=15 2:00s 1:00 S -Rule Norway 1959 1965 - Sep Sun>=15 2:00s 0 - -Rule Norway 1965 only - Apr 25 2:00s 1:00 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Europe/Oslo 0:43:00 - LMT 1895 Jan 1 - 1:00 Norway CE%sT 1940 Aug 10 23:00 - 1:00 C-Eur CE%sT 1945 Apr 2 2:00 - 1:00 Norway CE%sT 1980 - 1:00 EU CE%sT - -# 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 -# and -# ). 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 -# ) 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 "inhabited" 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 (2013-09-04): -# -# Actually, Jan Mayen was never occupied by Germany during World War II, -# so it must have diverged from Oslo time during the war, as Oslo was -# keeping Berlin time. -# -# 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 attacks from Germans. In 1943 the Americans established a -# radiolocating station on the island, called "Atlantic City". Possibly -# the UT 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 -# ). The Svalbard FAQ -# 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.ucalgary.ca/UofC/departments/UP/1-55238/1-55238-110-2.html -# 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, so use Europe/Oslo -# for these regions. -Link Europe/Oslo Arctic/Longyearbyen - -# Poland - -# The 1919 dates and times can be found in Tygodnik Urzędowy nr 1 (1919-03-20), -# pp 1-2. - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Poland 1918 1919 - Sep 16 2:00s 0 - -Rule Poland 1919 only - Apr 15 2:00s 1:00 S -Rule Poland 1944 only - Apr 3 2:00s 1:00 S -# Whitman gives 1944 Nov 30; go with Shanks & Pottenger. -Rule Poland 1944 only - Oct 4 2:00 0 - -# For 1944-1948 Whitman gives the previous day; go with Shanks & Pottenger. -Rule Poland 1945 only - Apr 29 0:00 1:00 S -Rule Poland 1945 only - Nov 1 0:00 0 - -# For 1946 on the source is Kazimierz Borkowski, -# Toruń Center for Astronomy, Dept. of Radio Astronomy, Nicolaus Copernicus U., -# https://www.astro.uni.torun.pl/~kb/Artykuly/U-PA/Czas2.htm#tth_tAb1 -# Thanks to Przemysław Augustyniak (2005-05-28) for this reference. -# He also gives these further references: -# Mon Pol nr 13, poz 162 (1995) -# Druk nr 2180 (2003) -Rule Poland 1946 only - Apr 14 0:00s 1:00 S -Rule Poland 1946 only - Oct 7 2:00s 0 - -Rule Poland 1947 only - May 4 2:00s 1:00 S -Rule Poland 1947 1949 - Oct Sun>=1 2:00s 0 - -Rule Poland 1948 only - Apr 18 2:00s 1:00 S -Rule Poland 1949 only - Apr 10 2:00s 1:00 S -Rule Poland 1957 only - Jun 2 1:00s 1:00 S -Rule Poland 1957 1958 - Sep lastSun 1:00s 0 - -Rule Poland 1958 only - Mar 30 1:00s 1:00 S -Rule Poland 1959 only - May 31 1:00s 1:00 S -Rule Poland 1959 1961 - Oct Sun>=1 1:00s 0 - -Rule Poland 1960 only - Apr 3 1:00s 1:00 S -Rule Poland 1961 1964 - May lastSun 1:00s 1:00 S -Rule Poland 1962 1964 - Sep lastSun 1:00s 0 - -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone Europe/Warsaw 1:24:00 - LMT 1880 - 1:24:00 - WMT 1915 Aug 5 # Warsaw Mean Time - 1:00 C-Eur CE%sT 1918 Sep 16 3:00 - 2:00 Poland EE%sT 1922 Jun - 1:00 Poland CE%sT 1940 Jun 23 2:00 - 1:00 C-Eur CE%sT 1944 Oct - 1:00 Poland CE%sT 1977 - 1:00 W-Eur CE%sT 1988 - 1:00 EU CE%sT - -# Portugal -# -# From Paul Eggert (2014-08-11), after a heads-up from Stephen Colebourne: -# According to a Portuguese decree (1911-05-26) -# https://dre.pt/application/dir/pdf1sdip/1911/05/12500/23132313.pdf -# Lisbon was at -0:36:44.68, but switched to GMT on 1912-01-01 at 00:00. -# Round the old offset to -0:36:45.

Chernov. The rest is from Shanks & Pottenger, -# except we follow Chernov's report that 1992 DST transitions were Sat -# 23:00, not Sun 02:00s. -# -# From Stanislaw A. Kuzikowski (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 (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 (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.

Regions-violators, 1981-1982. -# Wikipedia refers to -# http://maps.monetonos.ru/maps/raznoe/Old_Maps/Old_Maps/Articles/022/3_1981.html -# http://besp.narod.ru/nauka_1981_3.htm -# -# The second link provides two articles scanned from the Nauka i Zhizn -# magazine No. 3, 1981 and a scan of the short article attributed to -# the Trud newspaper from February 1982. The first link provides the -# same Nauka i Zhizn articles converted to the text form (but misses -# time belt changes map). -# -# The second Nauka i Zhizn article says that in addition to -# introduction of summer time on 1981-04-01 there are some time belt -# border changes on 1981-10-01, mostly affecting Nenets Autonomous -# Okrug, Krasnoyarsk Krai, Yakutia, Magadan Oblast and Chukotka -# according to the provided map (colored one). In addition to that -# "time violators" (regions which were not using rules of the time -# belts in which they were located) would not be moving off the DST on -# 1981-10-01 to restore the decree time usage. (Komi ASSR was -# supposed to repeat that move in October 1982 to account for the 2 -# hour difference.) Map depicting "time violators" before 1981-10-01 -# is also provided. -# -# The article from Trud says that 1981-10-01 changes caused problems -# and some territories would be moved to pre-1981-10-01 time by not -# moving to summer time on 1982-04-01. Namely: Dagestan, -# Kabardino-Balkar, Kalmyk, Komi, Mari, Mordovian, North Ossetian, -# Tatar, Chechen-Ingush and Chuvash ASSR, Krasnodar and Stavropol -# krais, Arkhangelsk, Vladimir, Vologda, Voronezh, Gorky, Ivanovo, -# Kostroma, Lipetsk, Penza, Rostov, Ryazan, Tambov, Tyumen and -# Yaroslavl oblasts, Nenets and Evenk autonomous okrugs, Khatangsky -# district of Taymyr Autonomous Okrug. As a result Evenk Autonomous -# Okrug and Khatangsky district of Taymyr Autonomous Okrug would end -# up on Moscow+4, Tyumen Oblast on Moscow+2 and the rest on Moscow -# time. -# -# http://astrozet.net/files/Zones/DOC/RU/1980-925.txt -# attributes the 1982 changes to the Act of the Council of Ministers -# of the USSR No. 126 from 18.02.1982. 1980-925.txt also adds -# Udmurtia to the list of affected territories and lists Khatangsky -# district separately from Taymyr Autonomous Okrug. Probably erroneously. -# -# The affected territories are currently listed under Europe/Moscow, -# Asia/Yekaterinburg and Asia/Krasnoyarsk. -# -# 12. Udmurtia -# The fact that Udmurtia is depicted as a violator in the Nauka i -# Zhizn article hints at Izhevsk being on different time from -# Kuybyshev before 1981-10-01. Udmurtia is not mentioned in the 1989 act. -# http://astrozet.net/files/Zones/DOC/RU/1980-925.txt -# implies Udmurtia was on Moscow time after 1982-04-01. -# Wikipedia implies Udmurtia being on Moscow+1 until 1991. -# -# ... -# -# All Russian zones are supposed to have by default a -1 change at -# 1991-03-31 2:00 (cancellation of the decree time in the USSR) and a +1 -# change at 1992-01-19 2:00 (restoration of the decree time in Russia). -# -# There were some exceptions, though. -# Wikipedia says newspapers listed Astrakhan, Saratov, Kirov, Volgograd, -# Izhevsk, Grozny, Kazan and Samara as such exceptions for the 1992 -# change. (Different newspapers providing different lists.

Between 1848 and 1894 Geneva did not -# follow Bern Mean Time but kept its own local mean time. -# To represent this, an extra zone would be needed. -# -# From Alois Treindl (2013-09-11): -# The Federal regulations say -# https://www.admin.ch/opc/de/classified-compilation/20071096/index.html -# ... the meridian for Bern mean time ... is 7 degrees 26' 22.50". -# Expressed in time, it is 0h29m45.5s. - -# From Pierre-Yves Berger (2013-09-11): -# the "Circulaire du conseil fédéral" (December 11 1893) -# http://www.amtsdruckschriften.bar.admin.ch/viewOrigDoc.do?id=10071353 -# clearly states that the [1894-06-01] change should be done at midnight -# but if no one is present after 11 at night, could be postponed until one -# hour before the beginning of service. - -# From Paul Eggert (2013-09-11): -# Round BMT to the nearest even second, 0:29:46. -# -# We can find no reliable source for Shanks's assertion that all of Switzerland -# except Geneva switched to Bern Mean Time at 00:00 on 1848-09-12.

The timekeeping it gives the -# most detail for is postal and telegraph time: here, federal legislation (the -# "Bundesgesetz über die Erstellung von elektrischen Telegraphen") passed on -# 1851-11-23, and an official implementation notice was published 1853-07-16 -# (Bundesblatt 1853, Bd.

The key individual who made time zones -# work in the US was William Frederick Allen - railway engineer, -# managing editor of the Travelers' Guide, and secretary of the -# General Time Convention, a railway standardization group. Allen -# spent months in dialogs with scientific and railway leaders, -# developed a workable plan to institute time zones, and presented it -# to the General Time Convention on 1883-04-11, saying that his plan -# meant "local time would be practically abolished" - a plus for -# railway scheduling. By the next convention on 1883-10-11 nearly all -# railroads had agreed and it took effect on 1883-11-18 at 12:00. -# That Sunday was called the "day of two noons", as the eastern parts -# of the new zones observed noon twice. Allen witnessed the -# transition in New York City, writing: -# -# I heard the bells of St. Paul's strike on the old time. Four -# minutes later, obedient to the electrical signal from the Naval -# Observatory ... the time-ball made its rapid descent, the chimes -# of old Trinity rang twelve measured strokes, and local time was -# abandoned, probably forever. -# -# Most of the US soon followed suit.

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. - -# From Arthur David Olson (2005-08-22): -# Paul has been careful to use the "US" rules only in those locations -# that are part of the United States; this reflects the real scope of -# U.S. government action.

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 -# since sometime in the 1960s. - -# From Chris Walton (2006-06-26): -# The Saskatchewan time act which was last updated in 1996 is about 30 pages -# long and rather painful to read. -# http://www.qp.gov.sk.ca/documents/English/Statutes/Statutes/T14.pdf - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Regina 1918 only - Apr 14 2:00 1:00 D -Rule Regina 1918 only - Oct 27 2:00 0 S -Rule Regina 1930 1934 - May Sun>=1 0:00 1:00 D -Rule Regina 1930 1934 - Oct Sun>=1 0:00 0 S -Rule Regina 1937 1941 - Apr Sun>=8 0:00 1:00 D -Rule Regina 1937 only - Oct Sun>=8 0:00 0 S -Rule Regina 1938 only - Oct Sun>=1 0:00 0 S -Rule Regina 1939 1941 - Oct Sun>=8 0:00 0 S -Rule Regina 1942 only - Feb 9 2:00 1:00 W # War -Rule Regina 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule Regina 1945 only - Sep lastSun 2:00 0 S -Rule Regina 1946 only - Apr Sun>=8 2:00 1:00 D -Rule Regina 1946 only - Oct Sun>=8 2:00 0 S -Rule Regina 1947 1957 - Apr lastSun 2:00 1:00 D -Rule Regina 1947 1957 - Sep lastSun 2:00 0 S -Rule Regina 1959 only - Apr lastSun 2:00 1:00 D -Rule Regina 1959 only - Oct lastSun 2:00 0 S -# -Rule Swift 1957 only - Apr lastSun 2:00 1:00 D -Rule Swift 1957 only - Oct lastSun 2:00 0 S -Rule Swift 1959 1961 - Apr lastSun 2:00 1:00 D -Rule Swift 1959 only - Oct lastSun 2:00 0 S -Rule Swift 1960 1961 - Sep lastSun 2:00 0 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone America/Regina -6:58:36 - LMT 1905 Sep - -7:00 Regina M%sT 1960 Apr lastSun 2:00 - -6:00 - CST -Zone America/Swift_Current -7:11:20 - LMT 1905 Sep - -7:00 Canada M%sT 1946 Apr lastSun 2:00 - -7:00 Regina M%sT 1950 - -7:00 Swift M%sT 1972 Apr lastSun 2:00 - -6:00 - CST - - -# Alberta - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule Edm 1918 1919 - Apr Sun>=8 2:00 1:00 D -Rule Edm 1918 only - Oct 27 2:00 0 S -Rule Edm 1919 only - May 27 2:00 0 S -Rule Edm 1920 1923 - Apr lastSun 2:00 1:00 D -Rule Edm 1920 only - Oct lastSun 2:00 0 S -Rule Edm 1921 1923 - Sep lastSun 2:00 0 S -Rule Edm 1942 only - Feb 9 2:00 1:00 W # War -Rule Edm 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule Edm 1945 only - Sep lastSun 2:00 0 S -Rule Edm 1947 only - Apr lastSun 2:00 1:00 D -Rule Edm 1947 only - Sep lastSun 2:00 0 S -Rule Edm 1967 only - Apr lastSun 2:00 1:00 D -Rule Edm 1967 only - Oct lastSun 2:00 0 S -Rule Edm 1969 only - Apr lastSun 2:00 1:00 D -Rule Edm 1969 only - Oct lastSun 2:00 0 S -Rule Edm 1972 1986 - Apr lastSun 2:00 1:00 D -Rule Edm 1972 2006 - Oct lastSun 2:00 0 S -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -Zone America/Edmonton -7:33:52 - LMT 1906 Sep - -7:00 Edm M%sT 1987 - -7:00 Canada M%sT - - -# British Columbia - -# From Paul Eggert (2006-03-22): -# Shanks & Pottenger write that since 1970 most of this region has -# been like Vancouver. -# Dawson Creek uses MST.

Igloolik [was similar but then] -# made the switch to central time on Saturday, Nov. 6. - -# From Paul Eggert (2000-10-02): -# Matthews and Vincent (1998) say the following, but we lack histories -# for these potential new Zones. -# -# The Canadian Forces station at Alert uses Eastern Time while the -# handful of residents at the Eureka weather station [in the Central -# zone] skip daylight savings.

I'm -# checking for more info, and will get back to you if I come up with -# more. -# [Also see (2001-03-09).] - -# From Gwillim Law (2005-05-21): -# According to ... -# http://www.canadiangeographic.ca/Magazine/SO98/geomap.asp -# (from a 1998 Canadian Geographic article), the de facto and de jure time -# for Southampton Island (at the north end of Hudson Bay) is UTC-5 all year -# round. Using Google, it's easy to find other websites that confirm this. -# I wasn't able to find how far back this time regimen goes, but since it -# predates the creation of Nunavut, it probably goes back many years.... -# The Inuktitut name of Coral Harbour is Sallit, but it's rarely used. -# -# From Paul Eggert (2014-10-17): -# For lack of better information, assume that Southampton Island observed -# daylight saving only during wartime. Gwillim Law's email also -# mentioned maps now maintained by National Research Council Canada; -# see above for an up-to-date link. - -# From Chris Walton (2007-03-01): -# ... the community of Resolute (located on Cornwallis Island in -# Nunavut) moved from Central Time to Eastern Time last November. -# Basically the community did not change its clocks at the end of -# daylight saving.... -# http://www.nnsl.com/frames/newspapers/2006-11/nov13_06none.html - -# From Chris Walton (2011-03-21): -# Back in 2007 I initiated the creation of a new "zone file" for Resolute -# Bay. Resolute Bay is a small community located about 900km north of -# the Arctic Circle. The zone file was required because Resolute Bay had -# decided to use UTC-5 instead of UTC-6 for the winter of 2006-2007. -# -# According to new information which I received last week, Resolute Bay -# went back to using UTC-6 in the winter of 2007-2008... -# -# On March 11/2007 most of Canada went onto daylight saving. On March -# 14/2007 I phoned the Resolute Bay hamlet office to do a "time check." I -# talked to somebody that was both knowledgeable and helpful. I was able -# to confirm that Resolute Bay was still operating on UTC-5. It was -# explained to me that Resolute Bay had been on the Eastern Time zone -# (EST) in the winter, and was now back on the Central Time zone (CDT). -# i.e. the time zone had changed twice in the last year but the clocks -# had not moved. The residents had to know which time zone they were in -# so they could follow the correct TV schedule... -# -# On Nov 02/2008 most of Canada went onto standard time. On Nov 03/2008 I -# phoned the Resolute Bay hamlet office...[D]ue to the challenging nature -# of the phone call, I decided to seek out an alternate source of -# information. I found an e-mail address for somebody by the name of -# Stephanie Adams whose job was listed as "Inns North Support Officer for -# Arctic Co-operatives." I was under the impression that Stephanie lived -# and worked in Resolute Bay... -# -# On March 14/2011 I phoned the hamlet office again. I was told that -# Resolute Bay had been using Central Standard Time over the winter of -# 2010-2011 and that the clocks had therefore been moved one hour ahead -# on March 13/2011. The person I talked to was aware that Resolute Bay -# had previously experimented with Eastern Standard Time but he could not -# tell me when the practice had stopped. -# -# On March 17/2011 I searched the Web to find an e-mail address of -# somebody that might be able to tell me exactly when Resolute Bay went -# off Eastern Standard Time. I stumbled on the name "Aziz Kheraj." Aziz -# used to be the mayor of Resolute Bay and he apparently owns half the -# businesses including "South Camp Inn." This website has some info on -# Aziz: -# http://www.uphere.ca/node/493 -# -# I sent Aziz an e-mail asking when Resolute Bay had stopped using -# Eastern Standard Time. -# -# Aziz responded quickly with this: "hi, The time was not changed for the -# 1 year only, the following year, the community went back to the old way -# of "spring ahead-fall behind" currently we are zulu plus 5 hrs and in -# the winter Zulu plus 6 hrs" -# -# This of course conflicted with everything I had ascertained in November 2008. -# -# I sent Aziz a copy of my 2008 e-mail exchange with Stephanie. Aziz -# responded with this: "Hi, Stephanie lives in Winnipeg. I live here, You -# may want to check with the weather office in Resolute Bay or do a -# search on the weather through Env. Canada. web site" -# -# If I had realized the Stephanie did not live in Resolute Bay I would -# never have contacted her. I now believe that all the information I -# obtained in November 2008 should be ignored... -# I apologize for reporting incorrect information in 2008. - -# Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S -Rule NT_YK 1918 only - Apr 14 2:00 1:00 D -Rule NT_YK 1918 only - Oct 27 2:00 0 S -Rule NT_YK 1919 only - May 25 2:00 1:00 D -Rule NT_YK 1919 only - Nov 1 0:00 0 S -Rule NT_YK 1942 only - Feb 9 2:00 1:00 W # War -Rule NT_YK 1945 only - Aug 14 23:00u 1:00 P # Peace -Rule NT_YK 1945 only - Sep 30 2:00 0 S -Rule NT_YK 1965 only - Apr lastSun 0:00 2:00 DD -Rule NT_YK 1965 only - Oct lastSun 2:00 0 S -Rule NT_YK 1980 1986 - Apr lastSun 2:00 1:00 D -Rule NT_YK 1980 2006 - Oct lastSun 2:00 0 S -Rule NT_YK 1987 2006 - Apr Sun>=1 2:00 1:00 D -# Zone NAME GMTOFF RULES FORMAT [UNTIL] -# aka Panniqtuuq -Zone America/Pangnirtung 0 - -00 1921 # trading post est. - -4:00 NT_YK A%sT 1995 Apr Sun>=1 2:00 - -5:00 Canada E%sT 1999 Oct 31 2:00 - -6:00 Canada C%sT 2000 Oct 29 2:00 - -5:00 Canada E%sT -# formerly Frobisher Bay -Zone America/Iqaluit 0 - -00 1942 Aug # Frobisher Bay est. - -5:00 NT_YK E%sT 1999 Oct 31 2:00 - -6:00 Canada C%sT 2000 Oct 29 2:00 - -5:00 Canada E%sT -# aka Qausuittuq -Zone America/Resolute 0 - -00 1947 Aug 31 # Resolute founded - -6:00 NT_YK C%sT 2000 Oct 29 2:00 - -5:00 - EST 2001 Apr 1 3:00 - -6:00 Canada C%sT 2006 Oct 29 2:00 - -5:00 - EST 2007 Mar 11 3:00 - -6:00 Canada C%sT -# aka Kangiqiniq -Zone America/Rankin_Inlet 0 - -00 1957 # Rankin Inlet founded - -6:00 NT_YK C%sT 2000 Oct 29 2:00 - -5:00 - EST 2001 Apr 1 3:00 - -6:00 Canada C%sT -# aka Iqaluktuuttiaq -Zone America/Cambridge_Bay 0 - -00 1920 # trading post est.? - -7:00 NT_YK M%sT 1999 Oct 31 2:00 - -6:00 Canada C%sT 2000 Oct 29 2:00 - -5:00 - EST 2000 Nov 5 0:00 - -6:00 - CST 2001 Apr 1 3:00 - -7:00 Canada M%sT -Zone America/Yellowknife 0 - -00 1935 # Yellowknife founded? - -7:00 NT_YK M%sT 1980 - -7:00 Canada M%sT -Zone America/Inuvik 0 - -00 1953 # Inuvik founded - -8:00 NT_YK P%sT 1979 Apr lastSun 2:00 - -7:00 NT_YK M%sT 1980 - -7:00 Canada M%sT -Zone America/Whitehorse -9:00:12 - LMT 1900 Aug 20 - -9:00 NT_YK Y%sT 1967 May 28 0:00 - -8:00 NT_YK P%sT 1980 - -8:00 Canada P%sT -Zone America/Dawson -9:17:40 - LMT 1900 Aug 20 - -9:00 NT_YK Y%sT 1973 Oct 28 0:00 - -8:00 NT_YK P%sT 1980 - -8:00 Canada P%sT - - -############################################################################### - -# Mexico - -# From Paul Eggert (2014-12-07): -# The Investigation and Analysis Service of the -# Mexican Library of Congress (MLoC) has published a -# history of Mexican local time (in Spanish) -# http://www.diputados.gob.mx/bibliot/publica/inveyana/polisoc/horver/index.htm -# -# Here are the discrepancies between Shanks & Pottenger (S&P) and the MLoC. -# (In all cases we go with the MLoC.) -# S&P report that Baja was at -8:00 in 1922/1923. -# S&P say the 1930 transition in Baja was 1930-11-16. -# S&P report no DST during summer 1931. -# S&P report a transition at 1932-03-30 23:00, not 1932-04-01. - -# From Gwillim Law (2001-02-20): -# There are some other discrepancies between the Decrees page and the -# tz database.

-# From Paul Eggert (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), Paraná (PR), São Paulo (SP), Rio de Janeiro (RJ), -# Espírito Santo (ES), Minas Gerais (MG), Bahia (BA), Goiás (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 Goiás 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 Amapá (AP), Ceará (CE), -# Maranhão (MA), Paraíba (PR), Pernambuco (PE), Piauí (PI), and Rio Grande do -# Norte (RN), and the eastern part of Pará (PA) are all in BR1 without DST. - -# From Marcos Tadeu (1998-09-27): -# Brazilian official page - -# From Jesper Nørgaard (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 Rodrigo Severo (2004-10-04): -# It's just the biannual change made necessary by the much hyped, supposedly -# modern Brazilian eletronic voting machines which, apparently, can't deal -# with a time change between the first and the second rounds of the elections. - -# From Steffen Thorsen (2007-09-20): -# Brazil will start DST on 2007-10-14 00:00 and end on 2008-02-17 00:00: -# http://www.mme.gov.br/site/news/detail.do;jsessionid=BBA06811AFCAAC28F0285210913513DA?newsId=13975 - -# From Paul Schulze (2008-06-24): -# ...by law number 11.662 of April 24, 2008 (published in the "Diario -# Oficial da União"...) in Brazil there are changes in the timezones, -# effective today (00:00am at June 24, 2008) as follows: -# -# a) The timezone UTC+5 is extinguished, with all the Acre state and the -# part of the Amazonas state that had this timezone now being put to the -# timezone UTC+4 -# b) The whole Pará state now is put at timezone UTC+3, instead of just -# part of it, as was before. -# -# This change follows a proposal of senator Tiao Viana of Acre state, that -# proposed it due to concerns about open television channels displaying -# programs inappropriate to youths in the states that had the timezone -# UTC+5 too early in the night. In the occasion, some more corrections -# were proposed, trying to unify the timezones of any given state. This -# change modifies timezone rules defined in decree 2.784 of 18 June, -# 1913. - -# From Rodrigo Severo (2008-06-24): -# Just correcting the URL: -# https://www.in.gov.br/imprensa/visualiza/index.jsp?jornal=do&secao=1&pagina=1&data=25/04/2008 -# -# As a result of the above Decree I believe the America/Rio_Branco -# timezone shall be modified from UTC-5 to UTC-4 and a new timezone shall -# be created to represent the...west side of the Pará State.
