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

162 # From Guy Harris:
163 # People's Republic of China. Yes, they really have only one time zone.
164
165 # From Bob Devine (1988-01-28):
166 # No they don't. See TIME mag, 1986-02-17 p.52. Even though
167 # China is across 4 physical time zones, before Feb 1, 1986 only the
168 # Peking (Bejing) time zone was recognized. Since that date, China
169 # has two of 'em -- Peking's and Urumqi (named after the capital of
170 # the Xinjiang Uighur Autonomous Region). I don't know about DST for it.
171 #
172 # . . .I just deleted the DST table and this editor makes it too
173 # painful to suck in another copy.. So, here is what I have for

510 # From Ephraim Silverberg (1996-01-02):
511 #
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 has
521 # been from midnight Thursday night to 1 a.m. Friday morning and the change
522 # back to standard time on 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 takes place on Sunday night instead of Saturday
525 # night to avoid conflicts with the Jewish New Year.
