From bb7c8f99ac829c5fe5d3bd3a20b2642d55abdb62 Mon Sep 17 00:00:00 2001 From: Tom Lane Date: Sat, 4 Oct 2014 14:18:29 -0400 Subject: [PATCH] Update time zone data files to tzdata release 2014h. Most zones in the Russian Federation are subtracting one or two hours as of 2014-10-26. Update the meanings of the abbreviations IRKT, KRAT, MAGT, MSK, NOVT, OMST, SAKT, VLAT, YAKT, YEKT to match. The IANA timezone database has adopted abbreviations of the form AxST/AxDT for all Australian time zones, reflecting what they believe to be current majority practice Down Under. These names do not conflict with usage elsewhere (other than ACST for Acre Summer Time, which has been in disuse since 1994). Accordingly, adopt these names into our "Default" timezone abbreviation set. The "Australia" abbreviation set now contains only CST,EAST,EST,SAST,SAT,WST, all of which are thought to be mostly historical usage. Note that SAST has also been changed to be South Africa Standard Time in the "Default" abbreviation set. Add zone abbreviations SRET (Asia/Srednekolymsk) and XJT (Asia/Urumqi), and use WSST/WSDT for western Samoa. Also a DST law change in the Turks & Caicos Islands (America/Grand_Turk), and numerous corrections for historical time zone data. --- src/backend/utils/misc/postgresql.conf.sample | 2 +- src/timezone/data/africa | 522 +++---- src/timezone/data/antarctica | 134 +- src/timezone/data/asia | 924 +++++------ src/timezone/data/australasia | 938 ++++++------ src/timezone/data/backward | 9 +- src/timezone/data/backzone | 477 ++++++ src/timezone/data/etcetera | 3 +- src/timezone/data/europe | 1358 ++++++++++------- src/timezone/data/factory | 1 - src/timezone/data/iso3166.tab | 12 +- src/timezone/data/leapseconds | 4 +- src/timezone/data/northamerica | 708 ++++----- src/timezone/data/pacificnew | 1 - src/timezone/data/southamerica | 484 +++--- src/timezone/data/systemv | 1 - src/timezone/data/yearistype.sh | 4 +- src/timezone/data/zone.tab | 69 +- src/timezone/data/zone1970.tab | 369 +++++ src/timezone/known_abbrevs.txt | 40 +- src/timezone/tznames/Africa.txt | 7 +- src/timezone/tznames/America.txt | 6 +- src/timezone/tznames/Antarctica.txt | 9 +- src/timezone/tznames/Asia.txt | 22 +- src/timezone/tznames/Australia | 26 +- src/timezone/tznames/Australia.txt | 61 +- src/timezone/tznames/Default | 69 +- src/timezone/tznames/Europe.txt | 5 +- src/timezone/tznames/Pacific.txt | 15 +- 29 files changed, 3572 insertions(+), 2708 deletions(-) create mode 100644 src/timezone/data/backzone create mode 100644 src/timezone/data/zone1970.tab diff --git a/src/backend/utils/misc/postgresql.conf.sample b/src/backend/utils/misc/postgresql.conf.sample index d109394d3b..8d5bb1961c 100644 --- a/src/backend/utils/misc/postgresql.conf.sample +++ b/src/backend/utils/misc/postgresql.conf.sample @@ -525,7 +525,7 @@ #timezone_abbreviations = 'Default' # Select the set of available time zone # abbreviations.

+# Guo Qingsheng (National Time-Service Center, CAS, Xi'an 710600, China)
+# Beijing Time at the Beginning of the PRC
+# China Historical Materials of Science and Technology
+# (Zhongguo ke ji shi liao, 中国科技史料), Vol. 24, No. 1 (2003)
+# It gives evidence that at the beginning of the PRC, Beijing time was
+# officially apparent solar time!  However, Guo also says that the
+# evidence is dubious, as the relevant institute of astronomy had not
+# been taken over by the PRC yet.  It's plausible that apparent solar
+# time was announced but never implemented, and that people continued
+# to use UT+8.  As the Shanghai radio station (and I presume the
+# observatory) was still under control of French missionaries, it
+# could well have ignored any such mandate.
+#
+# (2)
+# Guo Qing-sheng (Shaanxi Astronomical Observatory, CAS, Xi'an 710600, China)
+# A Study on the Standard Time Changes for the Past 100 Years in China
+# [undated and unknown publication location]
+# It says several things:
+#   * The Qing dynasty used local apparent solar time throughout China.
+#   * The Republic of China instituted Beijing mean solar time effective
+#     the official calendar book of 1914.
+#   * The French Concession in Shanghai set up signal stations in
+#     French docks in the 1890s, controlled by Xujiahui (Zikawei)
+#     Observatory and set to local mean time.
+#   * "From the end of the 19th century" it changed to UT+8.
+#   * Chinese Customs (by then reduced to a tool of foreign powers)
+#     eventually standardized on this time for all ports, and it
+#     became used by railways as well.
+#   * In 1918 the Central Observatory proposed dividing China into
+#     five time zones (see below for details).  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."  Guess that the
+# Xujiahui Observatory was under French control and stuck with UT+8.

+# this was based on what were apparently incorrect data in Shanks & Pottenger.

+# From Paul Eggert (2014-06-30):
+# In the early days of the PRC, Tibet was given its own time zone (UT+6) 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.  Approximate this lost history by a transition from LMT to
+# XJT at the start of 1928, the year of accession of the warlord Jin Shuren,
+# which happens to be the date given by Shanks & Pottenger (no doubt as a
+# guess) as the transition from LMT.  Ignore the usage of UT+8 before
+# 1986-02-01 under the theory that the transition date to UT+8 is unknown and
+# that the sort of users who prefer Asia/Urumqi now typically ignored the

+# Meiji Year 28 "The clause about standard time", mentioned that
+# Taiwan and Penghu Islands, as well as Yaeyama and Miyako Islands
+# (both in Okinawa) adopt the Western Standard Time which is based on
+# 120E. The adoption began from Jan 1, 1896. The original text can be
+# found on Wikisource:
+# http://ja.wikisource.org/wiki/標準時ニ關スル件_(公布時)
+# ... This could be the first adoption of time zone in Taiwan, because
+# during the Qing Dynasty, it seems that there was no time zone
+# declared officially.
+#
+# Later, in the beginning of World War II, on Sep 25, 1937, the Showa
+# Emperor announced Ordinance No. 529 of Showa Year 12 "The clause of
+# revision in the ordinance No. 167 of Meiji year 28 about standard
+# time", in which abolished the adoption of Western Standard Time in
+# western islands (listed above), which means the whole Japan

+# (UTC+9). The adoption began on Oct 1, 1937. The original text can

+# That is, the time zone of Taipei switched to UTC+9 on Oct 1, 1937.
+
+# From Yu-Cheng Chuang (2014-07-02):
+# I've found more evidence about when the time zone was switched from UTC+9
+# back to UTC+8 after WW2.  I believe it was on Sep 21, 1945.  In a document
+# during Japanese era [1] in which the officer told the staff to change time
+# zone back to Western Standard Time (UTC+8) on Sep 21.  And in another
+# history page of National Cheng Kung University [2], on Sep 21 there is a
+# note "from today, switch back to Western Standard Time".  From these two
+# materials, I believe that the time zone change happened on Sep 21.  And
+# today I have found another monthly journal called "The Astronomical Herald"
+# from The Astronomical Society of Japan [3] in which it mentioned the fact
+# that:
+#
+# 1. Standard Time of the Country (Japan) was adopted on Jan 1, 1888, using
+# the time at 135E (GMT+9)
+#
+# 2. Standard Time of the Country was renamed to Central Standard Time, on Jan
+# 1, 1898, and on the same day, the new territories Taiwan and Penghu islands,
+# as well as Yaeyama and Miyako islands, adopted a new time zone called
+# Western Standard Time, which is in GMT+8.
+#
+# 3. Western Standard Time was deprecated on Sep 30, 1937. From then all the
+# territories of Japan adopted the same time zone, which is Central Standard
+# Time.

+# has never been made official.  Richard P Hunt, in "Islam city yielding to
+# modern times", New York Times (1961-04-09), p 20, wrote that only airlines

+# time, doing so by setting their watches at sunrise to 6 o'clock (or to 12
+# o'clock for "Arab" time).
+#
+# The TZ database cannot represent quasi-solar time; airline time is the best
+# we can do.  The 1946 foreign air news digest of the U.S. Civil Aeronautics
+# Board (OCLC 42299995) reported that the "... Arabian Government, inaugurated

-# From Chuck Soper (2006-06-01):
-# I recently found this Australian government web page on time zones:
-# 
-# And this government web page lists time zone names and abbreviations:
-# 
-
-# 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 (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

+#   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.

+# Time Act in 1883 and including additional confirmation of some of
+# the dates of the 'Summer Time' orders originating at
+# Westminster.  There is a little uncertainty as to the starting date

+# This file is intended as a backward-compatibility aid for older programs.
+# New programs should use zone1970.tab.  This file is like zone1970.tab (see
+# zone1970.tab's comments), but with the following additional restrictions:
 #
-# This file contains a table where each row stands for an area that is
-# the intersection of a region identified by a country code and of a
-# zone where civil clocks have agreed since 1970.  The columns of the
-# table are as follows:
+# 1.  This file contains only ASCII characters.
+# 2.  The first data column contains exactly one country code.
 #
-# 1.  ISO 3166 2-character country code.  See the file 'iso3166.tab'.
-# 2.  Latitude and longitude of the area'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.
-#     Please see the 'Theory' file for how zone names are chosen.
-#     If multiple zones overlap a country, each has a row in the
-#     table, with column 1 being duplicated.
-# 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 areas first, where that does not contradict (1).
-#
-# Lines beginning with '#' are comments.
+# Because of (2), each row stands for an area that is the intersection
+# of a region identified by a country code and of a zone where civil
+# clocks have agreed since 1970; this is a narrower definition than
+# that of zone1970.tab.
