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).

223 # From Guy Harris:
224 # People's Republic of China. Yes, they really have only one time zone.
226 # From Bob Devine (1988-01-28):
227 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
228 # China is across 4 physical time zones, before Feb 1, 1986 only the
229 # Peking (Bejing) time zone was recognized. Since that date, China
230 # has two of 'em -- Peking's and Urumqi (named after the capital of
231 # the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
232 #
233 # . . .I just deleted the DST table and this editor makes it too
234 # painful to suck in another copy.. So, here is what I have for
235 # DST start/end dates for Peking's time zone (info from AP):

237 # 1986 May 4 - Sept 14
238 # 1987 mid-April - ??
240 # From U. S. Naval Observatory (1989-01-19):

244 # From Paul Eggert (2006-03-22):
245 # Shanks & Pottenger write that China (except for Hong Kong and Macau)
246 # has had a single time zone since 1980 May 1, observing summer DST
247 # from 1986 through 1991; this contradicts Devine's
248 # note about Time magazine, though apparently _something_ happened in 1986.

263 # historic timezones from some Taiwan websites. And yes, there are official
264 # Chinese names for these locales (before 1949).
265 #
266 # From Jesper Norgaard Welen (2006-07-14):
267 # I have investigated the timezones around 1970 on the
268 # http://www.astro.com/atlas site [with provinces and county
269 # boundaries summarized below].... A few other exceptions were two
270 # counties on the Sichuan side of the Xizang-Sichuan border,
271 # counties Dege and Baiyu which lies on the Sichuan side and are
272 # therefore supposed to be GMT+7, Xizang region being GMT+6, but Dege
273 # county is GMT+8 according to astro.com while Baiyu county is GMT+6
274 # (could be true), for the moment I am assuming that those two
275 # counties are mistakes in the astro.com data.
277 # From Paul Eggert (2008-02-11):
278 # I just now checked Google News for western news sources that talk
279 # about China's single time zone, and couldn't find anything before 1986
280 # talking about China being in one time zone. (That article was: Jim
281 # Mann, "A clumsy embrace for another western custom: China on daylight
282 # time--sort of", Los Angeles Times, 1986-05-05. By the way, this
283 # article confirms the tz database's data claiming that China began
284 # observing daylight saving time in 1986.
285 #
286 # From Thomas S. Mullaney (2008-02-11):
287 # I think you're combining two subjects that need to treated
288 # separately: daylight savings (which, you're correct, wasn't
289 # implemented until the 1980s) and the unified time zone centered near
290 # Beijing (which was implemented in 1949). Briefly, there was also a
291 # "Lhasa Time" in Tibet and "Urumqi Time" in Xinjiang. The first was
292 # ceased, and the second eventually recognized (again, in the 1980s).
293 #
294 # From Paul Eggert (2008-06-30):
295 # There seems to be a good chance China switched to a single time zone in 1949
296 # rather than in 1980 as Shanks & Pottenger have it, but we don't have a
297 # reliable documentary source saying so yet, so for now we still go with

436 # From Paul Eggert (1994-11-19):
437 # Today's _Economist_ (p 60) reports that Georgia moved its clocks forward
438 # an hour recently, due to a law proposed by Zurab Murvanidze,
439 # an MP who went on a hunger strike for 11 days to force discussion about it!
440 # We have no details, but we'll guess they didn't move the clocks back in fall.
441 #
442 # From Mathew Englander, quoting AP (1996-10-23 13:05-04):
443 # Instead of putting back clocks at the end of October, Georgia
444 # will stay on daylight savings time this winter to save energy,
445 # President Eduard Shevardnadze decreed Wednesday.
446 #
447 # From the BBC via Joseph S. Myers (2004-06-27):
448 #
449 # Georgia moved closer to Western Europe on Sunday... The former Soviet
450 # republic has changed its time zone back to that of Moscow. As a result it
451 # is now just four hours ahead of Greenwich Mean Time, rather than five hours
452 # ahead. The switch was decreed by the pro-Western president of Georgia,
453 # Mikhail Saakashvili, who said the change was partly prompted by the process
454 # of integration into Europe.
456 # From Teimuraz Abashidze (2005-11-07):
457 # Government of Georgia ... decided to NOT CHANGE daylight savings time on
458 # [Oct.] 30, as it was done before during last more than 10 years.
459 # Currently, we are in fact GMT +4:00, as before 30 October it was GMT
460 # +3:00.... The problem is, there is NO FORMAL LAW or governmental document
461 # about it. As far as I can find, I was told, that there is no document,
462 # because we just DIDN'T ISSUE document about switching to winter time....
463 # I don't know what can be done, especially knowing that some years ago our
464 # DST rules where changed THREE TIMES during one month.

581 # From Roozbeh Pournader (2003-03-15):
582 # This is an English translation of what I just found (originally in Persian).
583 # The Gregorian dates in brackets are mine:
584 #
585 # Official Newspaper No. 13548-1370/6/25 [1991-09-16]
586 # No. 16760/T233 H 1370/6/10 [1991-09-01]
587 #
588 # The Rule About Change of the Official Time of the Country
589 #
590 # The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
591 # based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
592 # of the Country's Organization for Official and Employment Affairs,
593 # and referring to the law for equating the working hours of workers
594 # and officers in the whole country dated 1359/4/23 [1980-07-14], and
595 # for synchronizing the official times of the country, agreed that:
596 #
597 # The official time of the country will should move forward one hour
598 # at the 24[:00] hours of the first day of Farvardin and should return
599 # to its previous state at the 24[:00] hours of the 30th day of
600 # Shahrivar.
601 #
602 # First Deputy to the President - Hassan Habibi
603 #
604 # From personal experience, that agrees with what has been followed
605 # for at least the last 5 years. Before that, for a few years, the
606 # date used was the first Thursday night of Farvardin and the last
607 # Thursday night of Shahrivar, but I can't give exact dates....
608 # I have also changed the abbreviations to what is considered correct
609 # here in Iran, IRST for regular time and IRDT for daylight saving time.
610 #
611 # From Roozbeh Pournader (2005-04-05):
612 # The text of the Iranian law, in effect since 1925, clearly mentions
613 # that the true solar year is the measure, and there is no arithmetic
614 # leap year calculation involved. There has never been any serious
615 # plan to change that law....
616 #
617 # From Paul Eggert (2006-03-22):
618 # Go with Shanks & Pottenger before Sept. 1991, and with Pournader thereafter.
619 # I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates,
620 # stopping after 2037 when 32-bit time_t's overflow.
621 # That cal-persia used Birashk's approximation, which disagrees with the solar
622 # calendar predictions for the year 2025, so I corrected those dates by hand.
623 #
624 # From Oscar van Vlijmen (2005-03-30), writing about future
625 # discrepancies between cal-persia and the Iranian calendar:
626 # For 2091 solar-longitude-after yields 2091-03-20 08:40:07.7 UT for
627 # the vernal equinox and that gets so close to 12:00 some local
628 # Iranian time that the definition of the correct location needs to be
629 # known exactly, amongst other factors. 2157 is even closer:
630 # 2157-03-20 08:37:15.5 UT. But the Gregorian year 2025 should give
631 # no interpretation problem whatsoever. By the way, another instant
632 # in the near future where there will be a discrepancy between
633 # arithmetical and astronomical Iranian calendars will be in 2058:
634 # vernal equinox on 2058-03-20 09:03:05.9 UT. The Java version of
635 # Reingold's/Dershowitz' calculator gives correctly the Gregorian date
636 # 2058-03-21 for 1 Farvardin 1437 (astronomical).
637 #
638 # From Steffen Thorsen (2006-03-22):
639 # Several of my users have reported that Iran will not observe DST anymore:
640 # http://www.irna.ir/en/news/view/line-17/0603193812164948.htm

720 # are an hour ahead of Baghdad."
721 #
722 # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
723 # In the past, some Kurdish nationalists, as a protest to the Iraqi
724 # Government, did not adhere to daylight saving time. They referred
725 # to daylight saving as Saddam time. But, as of today, the time zone

774 # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
775 # EEST Eastern Europe Standard Time [used by almost everyone else]
776 #
777 # Since timezones should be called by country and not capital cities,
778 # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
779 # EEST was equally unacceptable. Since "zonal" was not compatible with
780 # any other timezone abbreviation, I felt that 'IST' was the way to go
781 # and, indeed, it has received almost universal acceptance in timezone
782 # settings in Israeli computers.
783 #
784 # In any case, I am happy to share timezone abbreviations with India,
785 # high on my favorite-country list (and not only because my wife's

832 # (1997-03-04, 1998-03-16, 1998-12-28, 2000-01-17, 2000-07-25, 2004-12-22,
833 # and 2005-02-17):
835 # According to the Office of the Secretary General of the Ministry of
836 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
837 # One thing is entrenched in law, however: that there must be at least 150
838 # days of daylight savings time annually. From 1993-1998, the change to
839 # daylight savings time was on a Friday morning from midnight IST to
840 # 1 a.m IDT; up until 1998, the change back to standard time was on a
841 # Saturday night from midnight daylight savings time to 11 p.m. standard
842 # time. 1996 is an exception to this rule where the change back to standard
843 # time took place on Sunday night instead of Saturday night to avoid
844 # conflicts with the Jewish New Year. In 1999, the change to
845 # daylight savings time was still on a Friday morning but from
846 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
847 # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
848 # 1999 only. In the year 2000, the change to daylight savings time was
849 # similar to 1999, but although the change back will be on a Friday, it
850 # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
851 # changes to/from will take place at 1 a.m. old time, but now there is no
852 # rule as to what day of the week it will take place in as the start date
853 # (except in 2003) is the night after the Passover Seder (i.e. the eve
854 # of the 16th of Nisan in the lunar Hebrew calendar) and the end date
855 # (except in 2002) is three nights before Yom Kippur [Day of Atonement]

1011 # From Paul Eggert (1995-03-06):
1012 # Today's _Asahi Evening News_ (page 4) reports that Japan had
1013 # daylight saving between 1948 and 1951, but ``the system was discontinued
1014 # because the public believed it would lead to longer working hours.''
1016 # From Mayumi Negishi in the 2005-08-10 Japan Times
1017 # <http://www.japantimes.co.jp/cgi-bin/getarticle.pl5?nn20050810f2.htm>:
1018 # Occupation authorities imposed daylight-saving time on Japan on
1019 # [1948-05-01].... But lack of prior debate and the execution of
1020 # daylight-saving time just three days after the bill was passed generated
1021 # deep hatred of the concept.... The Diet unceremoniously passed a bill to
1022 # dump the unpopular system in October 1951, less than a month after the San
1023 # Francisco Peace Treaty was signed. (A government poll in 1951 showed 53%
1024 # of the Japanese wanted to scrap daylight-saving time, as opposed to 30% who
1025 # wanted to keep it.)

1034 # but the only locations using it (for birth certificates, presumably, since

1040 # 'Tokyo' usually stands for the former location of Tokyo Astronomical

1042 # This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'

1047 # From Hideyuki Suzuki (1998-11-16):
1048 # The ordinance No. 51 (1886) established "standard time" in Japan,
1049 # which stands for the time on E 135 degree.
1050 # In the ordinance No. 167 (1895), "standard time" was renamed to "central
1051 # standard time". And the same ordinance also established "western standard
1052 # time", which stands for the time on E 120 degree.... But "western standard
1053 # time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
1054 # 167, there is no mention regarding for what place western standard time is
1055 # standard....
1056 #
1057 # I wrote "ordinance" above, but I don't know how to translate.
1058 # In Japanese it's "chokurei", which means ordinance from emperor.
1060 # Shanks & Pottenger claim JST in use since 1896, and that a few

1167 # From Paul Eggert (1996-11-22):
1168 # Andrew Evtichov (1996-04-13) writes that Kazakhstan
1169 # stayed in sync with Moscow after 1990, and that Aqtobe (formerly Aktyubinsk)
1170 # and Aqtau (formerly Shevchenko) are the largest cities in their zones.
1171 # Guess that Aqtau and Aqtobe diverged in 1995, since that's the first time
1172 # IATA SSIM mentions a third time zone in Kazakhstan.
1174 # From Paul Eggert (2006-03-22):
1175 # German Iofis, ELSI, Almaty (2001-10-09) reports that Kazakhstan uses
1176 # RussiaAsia rules, instead of switching at 00:00 as the IATA has it.
1177 # Go with Shanks & Pottenger, who have them always using RussiaAsia rules.
1178 # Also go with the following claims of Shanks & Pottenger:
1179 #
1180 # - Kazakhstan did not observe DST in 1991.
1181 # - Qyzylorda switched from +5:00 to +6:00 on 1992-01-19 02:00.
1182 # - Oral switched from +5:00 to +4:00 in spring 1989.
1184 # <a href="http://www.kazsociety.org.uk/news/2005/03/30.htm">
1185 # From Kazakhstan Embassy's News Bulletin #11 (2005-03-21):
1186 # </a>
1187 # The Government of Kazakhstan passed a resolution March 15 abolishing
1188 # daylight saving time citing lack of economic benefits and health
1189 # complications coupled with a decrease in productivity.
1190 #
1191 # From Branislav Kojic (in Astana) via Gwillim Law (2005-06-28):
1192 # ... what happened was that the former Kazakhstan Eastern time zone
1193 # was "blended" with the Central zone. Therefore, Kazakhstan now has
1194 # two time zones, and difference between them is one hour. The zone
1195 # closer to UTC is the former Western zone (probably still called the
1196 # same), encompassing four provinces in the west: Aqtobe, Atyrau,
1197 # Mangghystau, and West Kazakhstan. The other zone encompasses
1198 # everything else.... I guess that would make Kazakhstan time zones
1199 # de jure UTC+5 and UTC+6 respectively.

1568 # From Rives McDow (2002-03-13):
1569 # I have been advised that Pakistan has decided to adopt dst on a
1570 # TRIAL basis for one year, starting 00:01 local time on April 7, 2002
1571 # and ending at 00:01 local time October 6, 2002. This is what I was
1572 # told, but I believe that the actual time of change may be 00:00; the
1573 # 00:01 was to make it clear which day it was on.
1575 # From Paul Eggert (2002-03-15):
1576 # Jesper Norgaard found this URL:
1577 # http://www.pak.gov.pk/public/news/app/app06_dec.htm
1578 # (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
1579 # advance the clocks by one hour on the night between the first
1580 # Saturday and Sunday of April and revert to the original position on
1581 # 15th October each year". This agrees with McDow's 04-07 at 00:00,
1582 # but disagrees about the October transition, and makes it sound like
1583 # it's not on a trial basis. Also, the "between the first Saturday
1584 # and Sunday of April" phrase, if taken literally, means that the
1585 # transition takes place at 00:00 on the first Sunday on or after 04-02.

1687 # From Amos Shapir (1998-02-15):
1688 #
1689 # From 1917 until 1948-05-15, all of Palestine, including the parts now
1690 # known as the Gaza Strip and the West Bank, was under British rule.
1691 # Therefore the rules given for Israel for that period, apply there too...
1692 #
1693 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1694 # (except a short occupation by Israel from 1956-11 till 1957-03, but no
1695 # time zone was affected then). It was never formally annexed to Egypt,
1696 # though.
1697 #
1698 # The rest of Palestine was under Jordanian rule at that time, formally
1699 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1700 # the country's previous name of "the Hashemite Kingdom of the
1701 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
1702 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1703 # East Jerusalem.
1704 #
1705 # Both areas were occupied by Israel in June 1967, but not annexed (except
1706 # for East Jerusalem). They were on Israel time since then; there might
1707 # have been a Military Governor's order about time zones, but I'm not aware
1708 # of any (such orders may have been issued semi-annually whenever summer
1709 # time was in effect, but maybe the legal aspect of time was just neglected).
1710 #
1711 # The Palestinian Authority was established in 1993, and got hold of most
1712 # towns in the West Bank and Gaza by 1995. I know that in order to
1713 # demonstrate...independence, they have been switching to
1714 # summer time and back on a different schedule than Israel's, but I don't
1715 # know when this was started, or what algorithm is used (most likely the
1716 # Jordanian one).
1717 #
1718 # To summarize, the table should probably look something like that:
1719 #
1720 # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1721 # ------------+-----------+-----------+-----------+-----------
1722 # Israel | Zion | Zion | Zion | Zion
1723 # West bank | Zion | Jordan | Zion | Jordan
1724 # Gaza | Zion | Egypt | Zion | Jordan
1725 #
1726 # I guess more info may be available from the PA's web page (if/when they
1727 # have one).
1729 # From Paul Eggert (2006-03-22):
1730 # Shanks & Pottenger write that Gaza did not observe DST until 1957, but go
1731 # with Shapir and assume that it observed DST from 1940 through 1947,
1732 # and that it used Jordanian rules starting in 1996.
1733 # We don't yet need a separate entry for the West Bank, since
1734 # the only differences between it and Gaza that we know about
1735 # occurred before our cutoff date of 1970.
1736 # However, as we get more information, we may need to add entries
1737 # for parts of the West Bank as they transitioned from Israel's rules
1738 # to Palestine's rules. If you have more info about this, please
1739 # send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1741 # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1742 # forwarded by Ephraim Silverberg:
1743 #
1744 # Despite the fact that Israel changed over to daylight savings time
1745 # last week, the PLO Authority (PA) has decided not to turn its clocks
1746 # one-hour forward at this time. As a sign of independence from Israeli rule,
1747 # the PA has decided to implement DST in April.

1762 # From Steffen Thorsen (2005-11-23):

1786 # According to Steffen Thorsen's web site the Gaza Strip and the rest of the
1787 # Palestinian territories left DST early on 13.th. of September at 2:00.
1789 # From Paul Eggert (2007-09-20):
1790 # My understanding is that Gaza and the West Bank disagree even over when

1945 # <http://today.reuters.co.uk/news/newsArticle.aspx?type=scienceNews&storyID=2006-04-12T172228Z_01_COL295762_RTRIDST_0_SCIENCE-SRILANKA-TIME-DC.XML>
1946 # [The Tamil Tigers] never accepted the original 1996 time change and simply
1947 # kept their clocks set five and a half hours ahead of Greenwich Mean
1948 # Time (GMT), in line with neighbor India.
1949 # From Paul Eggert (2006-04-18):
1950 # People who live in regions under Tamil control can use [TZ='Asia/Kolkata'],
1951 # as that zone has agreed with the Tamil areas since our cutoff date of 1970.
1953 # From K Sethu (2006-04-25):
1954 # I think the abbreviation LKT originated from the world of computers at
1955 # the time of or subsequent to the time zone changes by SL Government
1956 # twice in 1996 and probably SL Government or its standardization
1957 # agencies never declared an abbreviation as a national standard.
1958 #
1959 # I recollect before the recent change the government annoucemments
1960 # mentioning it as simply changing Sri Lanka Standard Time or Sri Lanka
1961 # Time and no mention was made about the abbreviation.
1962 #
1963 # If we look at Sri Lanka Department of Government's "Official News
1964 # Website of Sri Lanka" ... http://www.news.lk/ we can see that they
1965 # use SLT as abbreviation in time stamp at the beginning of each news
1966 # item....
1967 #
1968 # Within Sri Lanka I think LKT is well known among computer users and
1969 # adminsitrators. In my opinion SLT may not be a good choice because the
1970 # nation's largest telcom / internet operator Sri Lanka Telcom is well
1971 # known by that abbreviation - simply as SLT (there IP domains are
1972 # slt.lk and sltnet.lk).
1973 #
1974 # But if indeed our government has adopted SLT as standard abbreviation
1975 # (that we have not known so far) then it is better that it be used for
1976 # all computers.
1978 # From Paul Eggert (2006-04-25):
1979 # One possibility is that we wait for a bit for the dust to settle down
1980 # and then see what people actually say in practice.
