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.

578 # From Ephraim Silverberg (2001-01-11):
580 # I coined "IST/IDT" circa 1988. Until then there were three
581 # different abbreviations in use:
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]
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.
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

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

752 # Minister of Interior Poraz has announced that he will respect the law
753 # passed in July 2000 (proposed at the time jointly by himself and
754 # then-MK David Azulai [Shas]) fixing the dates for 2000-2004. Hence,
755 # the dates for 2003 and 2004 remain unchanged....
757 # As far as 2005 and beyond, no dates have been set. However, the
758 # minister has mentioned that he wishes to propose to move Israel's
759 # timezone in 2005 from GMT+2 to GMT+3 and upon that have DST during
760 # the summer months (i.e. GMT+4). However, no legislation in this
761 # direction is expected until the latter part of 2004 which is a long
762 # time off in terms of Israeli politics.
765 # The latest rumour, however, is that in 2005, when the clock changes to
766 # Daylight Saving Time (date as yet unknown), the move will be a two-hour leap
767 # forward (from UTC+0200 to UTC+0400) and then, in the fall, the clock will
768 # move back only an hour to UTC+0300 thus effectively moving Israel's timezone
769 # from UTC+0200 to UTC+0300. However, no actual draft has been put before the
770 # Knesset (Israel's Parliament) though the intention is to do so this
774 # Even though the draft law for the above did pass the Ministerial Committee
775 # for Legislative Matters three months ago, it was voted down in today's

778 # the beginning of Passover holiday in the spring to after the Tabernacle
779 # holiday in the fall (i.e. the dates of which are governed by the Hebrew

1230 # The rest of Palestine was under Jordanian rule at that time, formally
1231 # annexed in 1950 as the West Bank (and the word "Trans" was dropped from
1232 # the country's previous name of "the Hashemite Kingdom of the
1233 # Trans-Jordan"). So the rules for Jordan for that time apply. Major
1234 # towns in that area are Nablus (Shchem), El-Halil (Hebron), Ramallah, and
1237 # Both areas were occupied by Israel in June 1967, but not annexed (except
1238 # for East Jerusalem). They were on Israel time since then; there might

1261 # From Paul Eggert (1998-02-25):
1262 # Shanks writes that Gaza did not observe DST until 1957, but we'll go
1263 # with Shapir and assume that it observed DST from 1940 through 1947,
1264 # and that it used Jordanian rules starting in 1996.
1265 # We don't yet need a separate entry for the West Bank, since
1266 # the only differences between it and Gaza that we know about
1267 # occurred before our cutoff date of 1970.
1268 # However, as we get more information, we may need to add entries
1269 # for parts of the West Bank as they transitioned from Israel's rules
1270 # to Palestine's rules. If you have more info about this, please
1271 # send it to tz@elsie.nci.nih.gov for incorporation into future editions.
1273 # From IINS News Service - Israel - 1998-03-23 10:38:07 Israel time,
1274 # forwarded by Ephraim Silverberg:
1276 # Despite the fact that Israel changed over to daylight savings time
1277 # last week, the PLO Authority (PA) has decided not to turn its clocks
1278 # one-hour forward at this time. As a sign of independence from Israeli rule,
1279 # the PA has decided to implement DST in April.
1281 # From Paul Eggert (1999-09-20):
1282 # Daoud Kuttab writes in
1283 # <a href="http://www.jpost.com/com/Archive/22.Apr.1999/Opinion/Article-2.html">
1285 # </a> (Jerusalem Post, 1999-04-22) that
1286 # the Palestinian National Authority changed to DST on 1999-04-15.
1287 # I vaguely recall that they switch back in October (sorry, forgot the source).
1288 # For now, let's assume that the spring switch was at 24:00,
1289 # and that they switch at 0:00 on the 3rd Fridays of April and October.
