13# From Guy Harris:
14# People's Republic of China.  Yes, they really have only one time zone.
15
16# From Bob Devine (January 28, 1988):
17# No they don't.  See TIME mag, February 17, 1986 p.52.  Even though
18# China is across 4 physical time zones, before Feb 1, 1986 only the
19# Peking (Bejing) time zone was recognized.  Since that date, China
20# has two of 'em -- Peking's and Urumqi (named after the capital of
21# the Xinjiang Uighur Autonomous Region).  I don't know about DST for it.
22#
23# . . .I just deleted the DST table and this editor makes it too
24# painful to suck in another copy..  So, here is what I have for
25# DST start/end dates for Peking's time zone (info from AP):

85
86# From Ephraim Silverberg (April 18, 1989):
87
88# Prior to 1989, the rules concerning Daylight Savings Time changed every
89# year; as information, regarding exact times and dates during this period,
90# is not readily available at the present time, the rules commence starting
91# with the year 1989.
92
93# From 1989 onwards the rules are as follows:
94#
95# 1. Daylight Savings Time commences midnight of the first Saturday night
96#    following the seven-day festival of Pesach (Passover).  The transition
97#    is from midnight Israel Standard Time to 1 a.m. Israel Daylight Savings
98#    time.  As the Pesach festival is dependent on the Lunar calendar (the
99#    first day is always on the 15th day of the month of Nisan), the rule
100#    changes every year on the Gregorian calendar.
101#
102# 2. Standard Time is reinstated on the Saturday night whereupon Jews
103#    following the Ashkenazi (European) rite begin to recite the Selichot
104#    (forgiveness) prayers prior to the Jewish Lunar New Year.  The transition
105#    is from midnight Israel Daylight Savings time to 11 p.m. Israel Standard
106#    Time.  The law (according to the Ashkenazi custom) concerning the
107#    commencement of the Selichot prayers is described in chapter 128, section
108#    5 of the "Code of Jewish Law," by Rabbi Shlomo Ganzfried (translated by
109#    Hyman E. Goldin):
110#
111#       Beginning with the Sunday [**] before Rosh Hashanah [***],
112#       we rise early for the service of Selichot (supplications for
113#       forgiveness).  If Rosh Hashanah occurs on Monday or Tuesday, we
114#       begin saying the Selichot from the Sunday of the preceding week.
115#
116#    This, too, varies from year to year on the Gregorian calendar and, thus,
117#    two explicit timezone rules are required for each Gregorian year.
118#
119#    [**] actually Saturday night as the Jewish day commences at nightfall.
120#    [***] the Jewish Lunar New Year.
