7 # From Paul Eggert <eggert@twinsun.com> (1999-03-22):
8 #
9 # A good source for time zone historical data outside the U.S. is
10 # Thomas G. Shanks, The International Atlas (5th edition),
11 # San Diego: ACS Publications, Inc. (1999).
12 #
13 # Gwillim Law writes that a good source
14 # for recent time zone data is the International Air Transport
15 # Association's Standard Schedules Information Manual (IATA SSIM),
16 # published semiannually. Law sent in several helpful summaries
17 # of the IATA's data after 1990.
18 #
19 # Except where otherwise noted, Shanks is the source for entries through 1990,
20 # and IATA SSIM is the source for entries after 1990.
21 #
22 # Another source occasionally used is Edward W. Whitman, World Time Differences,
23 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
24 # I found in the UCLA library.
25 #
26 # A reliable and entertaining source about time zones is
27 # Derek Howse, Greenwich time and longitude, Philip Wilson Publishers (1997).

29 # I invented the abbreviations marked `*' in the following table;

84 # From Paul Eggert (1999-10-29):
85 # Shanks has Yerevan switching to 3:00 (with Russian DST) in spring 1991,
86 # then to 4:00 with no DST in fall 1995, then readopting Russian DST in 1997.
87 # Go with Shanks, even when he disagrees with others. Edgar Der-Danieliantz
88 # <edd@AIC.NET> reported (1996-05-04) that Yerevan probably wouldn't use DST
89 # in 1996, though it did use DST in 1995. IATA SSIM (1991/1998) reports that
90 # Armenia switched from 3:00 to 4:00 in 1998 and observed DST after 1991,

168 # From Guy Harris:
169 # People's Republic of China. Yes, they really have only one time zone.
171 # From Bob Devine (1988-01-28):
172 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
173 # China is across 4 physical time zones, before Feb 1, 1986 only the
174 # Peking (Bejing) time zone was recognized. Since that date, China
175 # has two of 'em -- Peking's and Urumqi (named after the capital of
176 # the Xinjiang Uyghur Autonomous Region). I don't know about DST for it.
177 #
178 # . . .I just deleted the DST table and this editor makes it too
179 # painful to suck in another copy.. So, here is what I have for

189 # From Paul Eggert <eggert@twinsun.com> (1995-12-19):

409 # says that Indonesia's time zones changed on 1988-01-01. Looking at some

454 #
455 # The Board of Ministers, in the meeting dated 1370/5/23 [1991-08-14],
456 # based on the suggestion number 2221/D dated 1370/4/22 [1991-07-13]
457 # of the Country's Organization for Official and Employment Affairs,
458 # and referring to the law for equating the working hours of workers
459 # and officers in the whole country dated 1359/4/23 [1980-07-14], and
460 # for synchronizing the official times of the country, agreed that:
461 #
462 # The official time of the country will should move forward one hour
463 # at the 24[:00] hours of the first day of Farvardin and should return
464 # to its previous state at the 24[:00] hours of the 30th day of
465 # Shahrivar.
466 #
467 # First Deputy to the President - Hassan Habibi
468 #
469 # From personal experience, that agrees with what has been followed
470 # for at least the last 5 years. Before that, for a few years, the
471 # date used was the first Thursday night of Farvardin and the last
472 # Thursday night of Shahrivar, but I can't give exact dates....
473 # I have also changed the abbreviations to what is considered correct
474 # here in Iran, IRST for regular time and IRDT for daylight saving time.

477 # Go with Shanks before September 1991, and with Pournader thereafter.
478 # I used Ed Reingold's cal-persia in GNU Emacs 21.2 to check Persian dates.
479 # The Persian calendar is based on the sun, and dates after around 2050

542 # From Jonathan Lennox <lennox@cs.columbia.edu> (2000-06-12):
543 # An article in this week's Economist ("Inside the Saddam-free zone", p. 50 in
544 # the U.S. edition) on the Iraqi Kurds contains a paragraph:
545 # "The three northern provinces ... switched their clocks this spring and
546 # are an hour ahead of Baghdad."
547 #
548 # But Rives McDow (2000-06-18) quotes a contact in Iraqi-Kurdistan as follows:
549 # In the past, some Kurdish nationalists, as a protest to the Iraqi
550 # Government, did not adhere to daylight saving time. They referred
551 # to daylight saving as Saddam time. But, as of today, the time zone
552 # in Iraqi-Kurdistan is on standard time with Baghdad, Iraq.
553 #
554 # So we'll ignore the Economist's claim.

576 # Israel
578 # From Ephraim Silverberg (2001-01-11):
579 #
580 # I coined "IST/IDT" circa 1988. Until then there were three
581 # different abbreviations in use:
582 #
583 # JST Jerusalem Standard Time [Danny Braniss, Hebrew University]
584 # IZT Israel Zonal (sic) Time [Prof. Haim Papo, Technion]
585 # EEST Eastern Europe Standard Time [used by almost everyone else]
586 #
587 # Since timezones should be called by country and not capital cities,
588 # I ruled out JST. As Israel is in Asia Minor and not Eastern Europe,
589 # EEST was equally unacceptable. Since "zonal" was not compatible with
590 # any other timezone abbreviation, I felt that 'IST' was the way to go
591 # and, indeed, it has received almost universal acceptance in timezone
592 # settings in Israeli computers.
593 #
594 # In any case, I am happy to share timezone abbreviations with India,
595 # high on my favorite-country list (and not only because my wife's
596 # family is from India).

644 # According to the Office of the Secretary General of the Ministry of
645 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
646 # One thing is entrenched in law, however: that there must be at least 150
647 # days of daylight savings time annually. From 1993-1998, the change to
648 # daylight savings time was on a Friday morning from midnight IST to
649 # 1 a.m IDT; up until 1998, the change back to standard time was on a
650 # Saturday night from midnight daylight savings time to 11 p.m. standard
651 # time. 1996 is an exception to this rule where the change back to standard
652 # time took place on Sunday night instead of Saturday night to avoid
653 # conflicts with the Jewish New Year. In 1999, the change to
654 # daylight savings time was still on a Friday morning but from
655 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
656 # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
657 # 1999 only. In the year 2000, the change to daylight savings time was
658 # similar to 1999, but although the change back will be on a Friday, it
659 # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
660 # changes to/from will take place at 1 a.m. old time, but now there is no
661 # rule as to what day of the week it will take place in as the start date
662 # (except in 2003) is the night after the Passover Seder (i.e. the eve
663 # of the 16th of Nisan in the lunar Hebrew calendar) and the end date
664 # (except in 2002) is three nights before Yom Kippur [Day of Atonement]

772 # From Paul Eggert <eggert@twinsun.com> (1995-03-06):
773 # Today's _Asahi Evening News_ (page 4) reports that Japan had
774 # daylight saving between 1948 and 1951, but ``the system was discontinued
775 # because the public believed it would lead to longer working hours.''
776 # Shanks writes that daylight saving in Japan during those years was as follows:
777 # Rule NAME FROM TO TYPE IN ON AT SAVE LETTER/S

782 # but the only locations using it were US military bases.
783 # We go with Shanks and omit daylight saving in those years for Asia/Tokyo.
785 # From Hideyuki Suzuki (1998-11-09):
786 # 'Tokyo' usually stands for the former location of Tokyo Astronomical
787 # Observatory: E 139 44' 40".90 (9h 18m 58s.727), N 35 39' 16".0.
788 # This data is from 'Rika Nenpyou (Chronological Scientific Tables) 1996'
789 # edited by National Astronomical Observatory of Japan....
790 # JST (Japan Standard Time) has been used since 1888-01-01 00:00 (JST).
791 # The law is enacted on 1886-07-07.
793 # From Hideyuki Suzuki (1998-11-16):
794 # The ordinance No. 51 (1886) established "standard time" in Japan,
795 # which stands for the time on E 135 degree.
796 # In the ordinance No. 167 (1895), "standard time" was renamed to "central
797 # standard time". And the same ordinance also established "western standard
798 # time", which stands for the time on E 120 degree.... But "western standard
799 # time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
800 # 167, there is no mention regarding for what place western standard time is
801 # standard....
802 #
803 # I wrote "ordinance" above, but I don't know how to translate.
804 # In Japanese it's "chokurei", which means ordinance from emperor.
806 # Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)
807 # use +0800; go with Suzuki. Guess that all ordinances took effect on Jan 1.

1150 # From Rives McDow (2002-03-13):
1151 # I have been advised that Pakistan has decided to adopt dst on a
1152 # TRIAL basis for one year, starting 00:01 local time on April 7, 2002
1153 # and ending at 00:01 local time October 6, 2002. This is what I was
1154 # told, but I believe that the actual time of change may be 00:00; the
1155 # 00:01 was to make it clear which day it was on.
1157 # From Paul Eggert (2002-03-15):
1158 # Jesper Norgaard found this URL:
1159 # http://www.pak.gov.pk/public/news/app/app06_dec.htm
1160 # (dated 2001-12-06) which says that the Cabinet adopted a scheme "to
1161 # advance the clocks by one hour on the night between the first
1162 # Saturday and Sunday of April and revert to the original position on
1163 # 15th October each year". This agrees with McDow's 04-07 at 00:00,
1164 # but disagrees about the October transition, and makes it sound like
1165 # it's not on a trial basis. Also, the "between the first Saturday
1166 # and Sunday of April" phrase, if taken literally, means that the
1167 # transition takes place at 00:00 on the first Sunday on or after 04-02.
1169 # From Paul Eggert (2003-02-09):
1170 # DAWN <http://www.dawn.com/2002/10/06/top13.htm> reported on 2002-10-05

1176 #
1177 # ISLAMABAD, March 6: Information and Media Development Minister Sheikh
1178 # Rashid Ahmed on Thursday said the cabinet had reversed a previous
1179 # decision to advance clocks by one hour in summer and put them back by
1180 # one hour in winter with the aim of saving light hours and energy.

1199 # From Amos Shapir <amos@nsof.co.il> (1998-02-15):
1200 #
1201 # From 1917 until 1948-05-15, all of Palestine, including the parts now
1202 # known as the Gaza Strip and the West Bank, was under British rule.
1203 # Therefore the rules given for Israel for that period, apply there too...
1204 #
1205 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1206 # (except a short occupation by Israel from 1956-11 till 1957-03, but no
1207 # time zone was affected then). It was never formally annexed to Egypt,
1208 # though.
1209 #
1210 # The rest of Palestine was under Jordanian rule at that time, formally
1211 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1212 # the country's previous name of "the Hashemite Kingdom of the
1213 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
1214 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1215 # East Jerusalem.
1216 #
1217 # Both areas were occupied by Israel in June 1967, but not annexed (except
1218 # for East Jerusalem). They were on Israel time since then; there might
1219 # have been a Military Governor's order about time zones, but I'm not aware
1220 # of any (such orders may have been issued semi-annually whenever summer
1221 # time was in effect, but maybe the legal aspect of time was just neglected).
1222 #
1223 # The Palestinian Authority was established in 1993, and got hold of most
1224 # towns in the West Bank and Gaza by 1995. I know that in order to
1225 # demonstrate...independence, they have been switching to
1226 # summer time and back on a different schedule than Israel's, but I don't
1227 # know when this was started, or what algorithm is used (most likely the
1228 # Jordanian one).
1229 #
1230 # To summarize, the table should probably look something like that:
1231 #
1232 # Area \ when | 1918-1947 | 1948-1967 | 1967-1995 | 1996-
1233 # ------------+-----------+-----------+-----------+-----------
1234 # Israel | Zion | Zion | Zion | Zion
1235 # West bank | Zion | Jordan | Zion | Jordan
1236 # Gaza | Zion | Egypt | Zion | Jordan
1237 #
1238 # I guess more info may be available from the PA's web page (if/when they
1239 # have one).
1241 # From Paul Eggert (1998-02-25):
1242 # Shanks writes that Gaza did not observe DST until 1957, but we'll go
1243 # with Shapir and assume that it observed DST from 1940 through 1947,
1244 # and that it used Jordanian rules starting in 1996.
1245 # We don't yet need a separate entry for the West Bank, since
1246 # the only differences between it and Gaza that we know about
1247 # occurred before our cutoff date of 1970.
1248 # However, as we get more information, we may need to add entries
1249 # for parts of the West Bank as they transitioned from Israel's rules
1250 # to Palestine's rules. If you have more info about this, please
1251 # send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1253 # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1254 # forwarded by Ephraim Silverberg:
1255 #
1256 # Despite the fact that Israel changed over to daylight savings time
1257 # last week, the PLO Authority (PA) has decided not to turn its clocks
1258 # one-hour forward at this time. As a sign of independence from Israeli rule,
1259 # the PA has decided to implement DST in April.
