10 # From Paul Eggert (2006-03-22):
11 #
12 # A good source for time zone historical data outside the U.S. is
13 # Thomas G. Shanks and Rique Pottenger, The International Atlas (6th edition),
14 # San Diego: ACS Publications, Inc. (2003).
15 #
16 # Gwillim Law writes that a good source
17 # for recent time zone data is the International Air Transport
18 # Association's Standard Schedules Information Manual (IATA SSIM),
19 # published semiannually. Law sent in several helpful summaries
20 # of the IATA's data after 1990.
21 #
22 # Except where otherwise noted, Shanks & Pottenger is the source for
23 # entries through 1990, and IATA SSIM is the source for entries afterwards.
24 #
25 # Another source occasionally used is Edward W. Whitman, World Time Differences,
26 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
27 # I found in the UCLA library.
28 #
29 # A reliable and entertaining source about time zones is
30 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

233 # From Guy Harris:
234 # People's Republic of China. Yes, they really have only one time zone.
236 # From Bob Devine (1988-01-28):
237 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
238 # China is across 4 physical time zones, before Feb 1, 1986 only the
239 # Peking (Bejing) time zone was recognized. Since that date, China
240 # has two of 'em -- Peking's and Urumqi (named after the capital of
241 # the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
242 #
243 # . . .I just deleted the DST table and this editor makes it too
244 # painful to suck in another copy.. So, here is what I have for
245 # DST start/end dates for Peking's time zone (info from AP):

254 # From Paul Eggert (2006-03-22):
255 # Shanks & Pottenger write that China (except for Hong Kong and Macau)
256 # has had a single time zone since 1980 May 1, observing summer DST
257 # from 1986 through 1991; this contradicts Devine's

274 # Chinese names for these locales (before 1949).
275 #
276 # From Jesper Norgaard Welen (2006-07-14):
277 # I have investigated the timezones around 1970 on the
278 # http://www.astro.com/atlas site [with provinces and county
279 # boundaries summarized below].... A few other exceptions were two
280 # counties on the Sichuan side of the Xizang-Sichuan border,
281 # counties Dege and Baiyu which lies on the Sichuan side and are
282 # therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege
283 # county is GMT+8 according to astro.com while Baiyu county is GMT+6
284 # (could be true), for the moment I am assuming that those two
285 # counties are mistakes in the astro.com data.
287 # From Paul Eggert (2008-02-11):
288 # I just now checked Google News for western news sources that talk
289 # about China's single time zone, and couldn't find anything before 1986
290 # talking about China being in one time zone. (That article was: Jim
291 # Mann, "A clumsy embrace for another western custom: China on daylight
292 # time--sort of", Los Angeles Times, 1986-05-05. By the way, this
293 # article confirms the tz database's data claiming that China began
294 # observing daylight saving time in 1986.
295 #
296 # From Thomas S. Mullaney (2008-02-11):
297 # I think you're combining two subjects that need to treated
298 # separately: daylight savings (which, you're correct, wasn't
299 # implemented until the 1980s) and the unified time zone centered near
300 # Beijing (which was implemented in 1949). Briefly, there was also a
301 # "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
302 # ceased, and the second eventually recognized (again, in the 1980s).
303 #
304 # From Paul Eggert (2008-06-30):
305 # There seems to be a good chance China switched to a single time zone in 1949
306 # rather than in 1980 as Shanks & Pottenger have it, but we don't have a
307 # reliable documentary source saying so yet, so for now we still go with

446 # From Paul Eggert (1994-11-19):
447 # Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
448 # an hour recently, due to a law proposed by Zurab Murvanidze,
449 # an MP who went on a hunger strike for 11 days to force discussion about it!
450 # We have no details, but we'll guess they didn't move the clocks back in fall.
451 #
452 # From Mathew Englander, quoting AP (1996-10-23 13:05-04):
453 # Instead of putting back clocks at the end of October, Georgia
454 # will stay on daylight savings time this winter to save energy,
455 # President Eduard Shevardnadze decreed Wednesday.
456 #
457 # From the BBC via Joseph S. Myers (2004-06-27):
458 #
459 # Georgia moved closer to Western Europe on Sunday... The former Soviet
460 # republic has changed its time zone back to that of Moscow. As a result it
461 # is now just four hours ahead of Greenwich Mean Time, rather than five hours
462 # ahead. The switch was decreed by the pro-Western president of Georgia,
463 # Mikhail Saakashvili, who said the change was partly prompted by the process
464 # of integration into Europe.
466 # From Teimuraz Abashidze (2005-11-07):
467 # Government of Georgia ... decided to NOT CHANGE daylight savings time on
468 # [Oct.] 30, as it was done before during last more than 10 years.
469 # Currently, we are in fact GMT +4:00, as before 30 October it was GMT
470 # +3:00.... The problem is, there is NO FORMAL LAW or governmental document
471 # about it. As far as I can find, I was told, that there is no document,
472 # because we just DIDN'T ISSUE document about switching to winter time....
473 # I don't know what can be done, especially knowing that some years ago our
474 # DST rules where changed THREE TIMES during one month.

591 # From Roozbeh Pournader (2003-03-15):
592 # This is an English translation of what I just found (originally in Persian).
593 # The Gregorian dates in brackets are mine:
594 #
595 # Official Newspaper No. 13548-1370/6/25 [1991-09-16]
596 # No. 16760/T233 H 1370/6/10 [1991-09-01]
597 #
598 # The Rule About Change of the Official Time of the Country
599 #
600 # The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
601 # based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
602 # of the Country's Organization for Official and Employment Affairs,
603 # and referring to the law for equating the working hours of workers
604 # and officers in the whole country dated 1359/4/23 [1980-07-14], and
605 # for synchronizing the official times of the country, agreed that:
606 #
607 # The official time of the country will should move forward one hour
608 # at the 24[:00] hours of the first day of Farvardin and should return
609 # to its previous state at the 24[:00] hours of the 30th day of
610 # Shahrivar.
611 #
612 # First Deputy to the President - Hassan Habibi
613 #
614 # From personal experience, that agrees with what has been followed
615 # for at least the last 5 years. Before that, for a few years, the
616 # date used was the first Thursday night of Farvardin and the last
617 # Thursday night of Shahrivar, but I can't give exact dates....
618 # I have also changed the abbreviations to what is considered correct
619 # here in Iran, IRST for regular time and IRDT for daylight saving time.
620 #
621 # From Roozbeh Pournader (2005-04-05):
622 # The text of the Iranian law, in effect since 1925, clearly mentions
623 # that the true solar year is the measure, and there is no arithmetic
624 # leap year calculation involved. There has never been any serious
625 # plan to change that law....
626 #
627 # From Paul Eggert (2006-03-22):
628 # Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
629 # I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
630 # stopping after 2037 when 32-bit time_t's overflow.
631 # That cal-persia used Birashk's approximation, which disagrees with the solar
632 # calendar predictions for the year 2025, so I corrected those dates by hand.
633 #
634 # From Oscar van Vlijmen (2005-03-30), writing about future
635 # discrepancies between cal-persia and the Iranian calendar:
636 # For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
637 # the vernal equinox and that gets so close to 12:00 some local
638 # Iranian time that the definition of the correct location needs to be
639 # known exactly, amongst other factors. 2157 is even closer:
640 # 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
641 # no interpretation problem whatsoever. By the way, another instant
642 # in the near future where there will be a discrepancy between
643 # arithmetical and astronomical Iranian calendars will be in 2058:
644 # vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
645 # Reingold's/Dershowitz' calculator gives correctly the Gregorian date
646 # 2058-03-21 for 1 Farvardin 1437 (astronomical).
647 #
648 # From Steffen Thorsen (2006-03-22):
649 # Several of my users have reported that Iran will not observe DST anymore:
650 # http://www.irna.ir/en/news/view/line-17/0603193812164948.htm
651 #
652 # From Reuters (2007-09-16), with a heads-up from Jesper Norgaard Welen:

727 # An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in

729 # "The three northern provinces ... switched their clocks this spring and
730 # are an hour ahead of Baghdad."
731 #
732 # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
733 # In the past, some Kurdish nationalists, as a protest to the Iraqi
734 # Government, did not adhere to daylight saving time. They referred
735 # to daylight saving as Saddam time. But, as of today, the time zone
736 # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.

776 # Israel
778 # From Ephraim Silverberg (2001-01-11):
779 #
780 # I coined "IST/IDT" circa 1988. Until then there were three
781 # different abbreviations in use:
782 #
783 # JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
784 # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
785 # EEST Eastern Europe Standard Time [used by almost everyone else]
786 #
787 # Since timezones should be called by country and not capital cities,
788 # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
789 # EEST was equally unacceptable. Since "zonal" was not compatible with
790 # any other timezone abbreviation, I felt that 'IST' was the way to go
791 # and, indeed, it has received almost universal acceptance in timezone
792 # settings in Israeli computers.
793 #
794 # In any case, I am happy to share timezone abbreviations with India,
795 # high on my favorite-country list (and not only because my wife's
796 # family is from India).

841 # From Ephraim Silverberg
842 # (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
843 # and 2005-02-17):
845 # According to the Office of the Secretary General of the Ministry of
846 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
847 # One thing is entrenched in law, however: that there must be at least 150
848 # days of daylight savings time annually. From 1993-1998, the change to
849 # daylight savings time was on a Friday morning from midnight IST to
850 # 1 a.m IDT; up until 1998, the change back to standard time was on a
851 # Saturday night from midnight daylight savings time to 11 p.m. standard
852 # time. 1996 is an exception to this rule where the change back to standard
853 # time took place on Sunday night instead of Saturday night to avoid
854 # conflicts with the Jewish New Year. In 1999, the change to
855 # daylight savings time was still on a Friday morning but from
856 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
857 # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
858 # 1999 only. In the year 2000, the change to daylight savings time was
859 # similar to 1999, but although the change back will be on a Friday, it
860 # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
861 # changes to/from will take place at 1 a.m. old time, but now there is no
862 # rule as to what day of the week it will take place in as the start date
863 # (except in 2003) is the night after the Passover Seder (i.e. the eve
864 # of the 16th of Nisan in the lunar Hebrew calendar) and the end date
865 # (except in 2002) is three nights before Yom Kippur [Day of Atonement]
866 # (the eve of the 7th of Tishrei in the lunar Hebrew calendar).

1022 # Today's _Asahi Evening News_ (page 4) reports that Japan had
1023 # daylight saving between 1948 and 1951, but ``the system was discontinued
1024 # because the public believed it would lead to longer working hours.''

1028 # Occupation authorities imposed daylight-saving time on Japan on
1029 # [1948-05-01].... But lack of prior debate and the execution of
1030 # daylight-saving time just three days after the bill was passed generated
1031 # deep hatred of the concept.... The Diet unceremoniously passed a bill to
1032 # dump the unpopular system in October 1951, less than a month after the San
1033 # Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%

1061 # standard time". And the same ordinance also established "western standard
1062 # time", which stands for the time on E 120 degree.... But "western standard
1063 # time" was abolished in the ordinance No. 529 (1937). In the ordinance No.

1177 # From Paul Eggert (1996-11-22):
1178 # Andrew Evtichov (1996-04-13) writes that Kazakhstan
1179 # stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
1180 # and Aqtau (formerly Shevchenko) are the largest cities in their zones.
1181 # Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
1182 # IATA SSIM mentions a third time zone in Kazakhstan.
1184 # From Paul Eggert (2006-03-22):
1185 # German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
1186 # RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
1187 # Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
1188 # Also go with the following claims of Shanks & Pottenger:
1189 #
1190 # - Kazakhstan did not observe DST in 1991.
1191 # - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.

1202 # ... what happened was that the former Kazakhstan Eastern time zone
1203 # was "blended" with the Central zone. Therefore, Kazakhstan now has
1204 # two time zones, and difference between them is one hour. The zone
1205 # closer to UTC is the former Western zone (probably still called the
1206 # same), encompassing four provinces in the west: Aqtobe, Atyrau,
1207 # Mangghystau, and West Kazakhstan. The other zone encompasses

1578 # From Rives McDow (2002-03-13):
1579 # I have been advised that Pakistan has decided to adopt dst on a
1580 # TRIAL basis for one year, starting 00:01 local time on April 7, 2002
1581 # and ending at 00:01 local time October 6, 2002. This is what I was
1582 # told, but I believe that the actual time of change may be 00:00; the
1583 # 00:01 was to make it clear which day it was on.
1585 # From Paul Eggert (2002-03-15):

1587 # http://www.pak.gov.pk/public/news/app/app06_dec.htm
1588 # (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
1589 # advance the clocks by one hour on the night between the first
1590 # Saturday and Sunday of April and revert to the original position on
1591 # 15th October each year". This agrees with McDow's 04-07 at 00:00,
1592 # but disagrees about the October transition, and makes it sound like
1593 # it's not on a trial basis. Also, the "between the first Saturday
1594 # and Sunday of April" phrase, if taken literally, means that the
1595 # transition takes place at 00:00 on the first Sunday on or after 04-02.

1704 # From Amos Shapir (1998-02-15):
1705 #
1706 # From 1917 until 1948-05-15, all of Palestine, including the parts now
1707 # known as the Gaza Strip and the West Bank, was under British rule.
1708 # Therefore the rules given for Israel for that period, apply there too...
1709 #
1710 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1711 # (except a short occupation by Israel from 1956-11 till 1957-03, but no
1712 # time zone was affected then). It was never formally annexed to Egypt,
1713 # though.
1714 #
1715 # The rest of Palestine was under Jordanian rule at that time, formally
1716 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1717 # the country's previous name of "the Hashemite Kingdom of the
1718 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
1719 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1720 # East Jerusalem.
1721 #
1722 # Both areas were occupied by Israel in June 1967, but not annexed (except
1723 # for East Jerusalem). They were on Israel time since then; there might
1724 # have been a Military Governor's order about time zones, but I'm not aware
1725 # of any (such orders may have been issued semi-annually whenever summer
1726 # time was in effect, but maybe the legal aspect of time was just neglected).
1727 #
1728 # The Palestinian Authority was established in 1993, and got hold of most
1729 # towns in the West Bank and Gaza by 1995. I know that in order to
1730 # demonstrate...independence, they have been switching to
1731 # summer time and back on a different schedule than Israel's, but I don't
1732 # know when this was started, or what algorithm is used (most likely the
1733 # Jordanian one).
1734 #
1735 # To summarize, the table should probably look something like that:
1736 #
1737 # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1738 # ------------+-----------+-----------+-----------+-----------
1739 # Israel | Zion | Zion | Zion | Zion
1740 # West bank | Zion | Jordan | Zion | Jordan
1741 # Gaza | Zion | Egypt | Zion | Jordan
1742 #
1743 # I guess more info may be available from the PA's web page (if/when they
1744 # have one).
1746 # From Paul Eggert (2006-03-22):
1747 # Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
1748 # with Shapir and assume that it observed DST from 1940 through 1947,
1749 # and that it used Jordanian rules starting in 1996.
1750 # We don't yet need a separate entry for the West Bank, since
1751 # the only differences between it and Gaza that we know about
1752 # occurred before our cutoff date of 1970.
1753 # However, as we get more information, we may need to add entries
1754 # for parts of the West Bank as they transitioned from Israel's rules
1755 # to Palestine's rules. If you have more info about this, please
1756 # send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1758 # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1759 # forwarded by Ephraim Silverberg:
1760 #
1761 # Despite the fact that Israel changed over to daylight savings time
1762 # last week, the PLO Authority (PA) has decided not to turn its clocks
1763 # one-hour forward at this time. As a sign of independence from Israeli rule,
1764 # the PA has decided to implement DST in April.
1766 # From Paul Eggert (1999-09-20):
1767 # Daoud Kuttab writes in

1806 # From Paul Eggert (2007-09-20):
1807 # My understanding is that Gaza and the West Bank disagree even over when

1999 # [The Tamil Tigers] never accepted the original 1996 time change and simply

2001 # Time (GMT), in line with neighbor India.
2002 # From Paul Eggert (2006-04-18):
2003 # People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
2004 # as that zone has agreed with the Tamil areas since our cutoff date of 1970.
2006 # From K Sethu (2006-04-25):
2007 # I think the abbreviation LKT originated from the world of computers at
2008 # the time of or subsequent to the time zone changes by SL Government
2009 # twice in 1996 and probably SL Government or its standardization
2010 # agencies never declared an abbreviation as a national standard.
2011 #
2012 # I recollect before the recent change the government annoucemments
2013 # mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
2014 # Time and no mention was made about the abbreviation.
2015 #
2016 # If we look at Sri Lanka Department of Government's "Official News
2017 # Website of Sri Lanka" ... http://www.news.lk/ we can see that they
2018 # use SLT as abbreviation in time stamp at the beginning of each news
2019 # item....
2020 #
2021 # Within Sri Lanka I think LKT is well known among computer users and
2022 # adminsitrators. In my opinion SLT may not be a good choice because the
2023 # nation's largest telcom / internet operator Sri Lanka Telcom is well
2024 # known by that abbreviation - simply as SLT (there IP domains are
2025 # slt.lk and sltnet.lk).
2026 #
2027 # But if indeed our government has adopted SLT as standard abbreviation
2028 # (that we have not known so far) then it is better that it be used for
2029 # all computers.
2031 # From Paul Eggert (2006-04-25):
