7 # From Paul Eggert <eggert@twinsun.com> (1996-11-22):
9 # A good source for time zone historical data outside the U.S. is
10 # Thomas G. Shanks, The International Atlas (3rd edition),
11 # San Diego: ACS Publications, Inc. (1991).
12 # Except where otherwise noted, it is the source for the data below.
14 # Gwillim Law <LAW@encmail.encompass.com> writes that a good source
15 # for recent time zone data is the International Air Transport
16 # Association's Standard Schedules Information Manual (IATA SSIM),
17 # published semiannually. Law sent in several helpful summaries
18 # of the IATA's data after 1990.
20 # Except where otherwise noted, Shanks is the source for entries through 1990,
21 # and IATA SSIM is the source for entries after 1990.
23 # Another source occasionally used is Edward W. Whitman, World Time Differences,
24 # Whitman Publishing Co, 2 Niagara Av, Ealing, London (undated), which
25 # I found in the UCLA library.
27 # A reliable and entertaining source about time zones is
28 # Derek Howse, Greenwich time and the discovery of the longitude,
29 # Oxford University Press (1980).
31 # I invented the abbreviations marked `*' in the following table;
32 # the rest are from earlier versions of this file, or from other sources.
33 # Corrections are welcome!
36 # 2:00 EET EEST Eastern European Time

50 # Incorporates data for Singapore from Robert Elz' asia 1.1, as well as
51 # additional information from Tom Yap, Sun Microsystems Intercontinental
52 # Technical Support (including a page from the Official Airline Guide -

83 # but usno1995 has Armenia at 4:00 (with DST), and Edgar Der-Danieliantz
84 # <edd@AIC.NET> reported today that Yerevan probably won't use DST this year,

162 # From Bob Devine (1988-01-28):
163 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
164 # China is across 4 physical time zones, before Feb 1, 1986 only the
165 # Peking (Bejing) time zone was recognized. Since that date, China
166 # has two of 'em -- Peking's and Urumqi (named after the capital of
167 # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
169 # . . .I just deleted the DST table and this editor makes it too
170 # painful to suck in another copy.. So, here is what I have for

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

182 # observing summer DST from 1986 through 1991; this contradicts Devine's
183 # note about Time magazine, though apparently _something_ happened in 1986.

509 # From Ephraim Silverberg <ephraim@cs.huji.ac.il>
510 # (1997-03-04 and 1998-03-16):
512 # According to the Office of the Secretary General of the Ministry of
513 # Interior, there is NO set rule for Daylight-Savings/Standard time changes.
514 # Each year they decide anew what havoc to wreak on the country. However,
515 # there is a "supposed" set of rules which is subject to change depending
516 # on the party the Minister of Interior, the size of the coalition
517 # government, the phase of the moon and the direction of the wind. Hence,
518 # changes may need to be made on a semi-annual basis. One thing is entrenched
519 # in law, however: that there must be at least 150 days of daylight savings
520 # time annually. Ever since 1993, the change to daylight savings time is
521 # on a Thursday night from midnight IST to 1 a.m IDT. The change back to
522 # standard time is on a Saturday night from midnight daylight savings time
523 # to 11 p.m. standard time. 1996 is an exception to this rule where the
524 # change back to standard time took place on Sunday night instead of Saturday
525 # night to avoid conflicts with the Jewish New Year.

873 # Shanks writes that Gaza did not observe DST until 1957, but we'll go
874 # with Shapir and assume that it observed DST from 1940 through 1947,
875 # and that it used Jordanian rules starting in 1996.
876 # We don't yet need a separate entry for the West Bank, since
877 # the only differences between it and Gaza that we know about
878 # occurred before our cutoff date of 1970.
879 # However, as we get more information, we may need to add entries
880 # for parts of the West Bank as they transitioned from Israel's rules
881 # to Palestine's rules. If you have more info about this, please
