7 # From Paul Eggert <eggert@twinsun.com> (1999-03-22):
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).
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.
19 # Except where otherwise noted, Shanks is the source for entries through 1990,
20 # and IATA SSIM is the source for entries after 1990.
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.
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;
30 # the rest are from earlier versions of this file, or from other sources.

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.

539 # Government, did not adhere to daylight saving time. They referred
540 # to daylight saving as Saddam time. But, as of today, the time zone

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

633 # According to the Office of the Secretary General of the Ministry of
634 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
635 # One thing is entrenched in law, however: that there must be at least 150
636 # days of daylight savings time annually. From 1993-1998, the change to
637 # daylight savings time was on a Friday morning from midnight IST to
638 # 1 a.m IDT; up until 1998, the change back to standard time was on a
639 # Saturday night from midnight daylight savings time to 11 p.m. standard
640 # time. 1996 is an exception to this rule where the change back to standard
641 # time took place on Sunday night instead of Saturday night to avoid
642 # conflicts with the Jewish New Year. In 1999, the change to
643 # daylight savings time was still on a Friday morning but from
644 # 2 a.m. IST to 3 a.m. IDT; furthermore, the change back to standard time
645 # was also on a Friday morning from 2 a.m. IDT to 1 a.m. IST for
646 # 1999 only. In the year 2000, the change to daylight savings time was
647 # similar to 1999, but although the change back will be on a Friday, it
648 # will take place from 1 a.m. IDT to midnight IST. Starting in 2001, all
649 # changes to/from will take place at 1 a.m. old time, but now there is no
650 # rule as to what day of the week it will take place in as the start date
651 # (except in 2003) is the night after the Passover Seder (i.e. the eve
652 # of the 16th of Nisan in the lunar Hebrew calendar) and the end date

741 # The Israeli government today adopted a proposal by Minister of Interior
742 # Eli Yishai to shorten the period of Daylight Savings Time for the year
743 # 2002 (only -- the dates for 2003 and 2004 are, so far, unaffected).
745 # The proposed date to Daylight Savings Time is September 13, 2002 instead
746 # of the current date: October 7, 2002. The hour of changeover has not
750 # While today the Knesset passed the initial proposal to reduce DST by
751 # some three weeks, a new compromise is being worked out between
752 # Minister of Justice Meir Sheetrit and Minister of Interior Eli
753 # Yishai to revert to standard time for a period of 48-96 _hours_
754 # (sic) around the Yom Kippur fast day (September 15-16) and then go
755 # *back* to DST until the end of October. The details of the proposal
756 # have yet to be worked out, but the second and final readings of the
757 # bill have until July 24 to pass.
760 # Thanks go to Yitschak Goldberg from E&M for bringing this (Hebrew) article
763 # http://www.ynet.co.il/articles/0,7340,L-2019315,00.html
765 # Hence, the proposal to shorten DST was withdrawn yesterday and the timezone
766 # files that have been in effect since July 2000 are still valid for all of
769 # Please note that the article mentions that the Shas MK's intend to
770 # bring up their amendment for future years (2003 and beyond). What this
771 # means exactly is anyone's guess since there are no set dates yet beyond
772 # 2004 and the end day set for 2003 and 2004 is already the 7th of Tishrei
773 # (i.e. before the fast of Yom Kippur). The only thing they may want to
774 # change is the start date of DST in 2003 from Mar.28.03 (24th of Adar II)
775 # to Apr.18.03 (16th of Nisan) so that the Passover Seder will take place

1200 # Therefore the rules given for Israel for that period, apply there too...
1202 # The Gaza Strip was under Egyptian rule between 1948-05-15 until 1967-06-05
1203 # (except a short occupation by Israel from 1956-11 till 1957-03, but no

1207 # The rest of Palestine was under Jordanian rule at that time, formally
1208 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1209 # the country's previous name of "the Hashemite Kingdom of the
1210 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
1211 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1214 # Both areas were occupied by Israel in June 1967, but not annexed (except
1215 # for East Jerusalem). They were on Israel time since then; there might

1243 # the only differences between it and Gaza that we know about
1244 # occurred before our cutoff date of 1970.
1245 # However, as we get more information, we may need to add entries
