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

# People's Republic of China

# From Guy Harris:
# People's Republic of China.  Yes, they really have only one time zone.

# From Bob Devine (January 28, 1988):
# No they don't.  See TIME mag, February 17, 1986 p.52.  Even though
# China is across 4 physical time zones, before Feb 1, 1986 only the
# Peking (Bejing) time zone was recognized.  Since that date, China
# has two of 'em -- Peking's and Urumqi (named after the capital of
# the Xinjiang Uighur Autonomous Region).  I don't know about DST for it.
#
# . . .I just deleted the DST table and this editor makes it too
# painful to suck in another copy..  So, here is what I have for
# DST start/end dates for Peking's time zone (info from AP):
#
#     1986 May 4 - Sept 14
#     1987 mid-April - ??

# From U. S. Naval Observatory (January 19, 1989):
# CHINA               8 H  AHEAD OF UTC  ALL OF CHINA, INCL TAIWAN
# CHINA               9 H  AHEAD OF UTC  APR 17 - SEP 10

# Israel

# From U. S. Naval Observatory (January 19, 1989):
# ISRAEL              2 H  AHEAD OF UTC
# ISRAEL              3 H  AHEAD OF UTC  APR 10 - SEP 3

# From Ephraim Silverberg (April 18, 1989):

# Prior to 1989, the rules concerning Daylight Savings Time changed every
# year; as information, regarding exact times and dates during this period,
# is not readily available at the present time, the rules commence starting
# with the year 1989.

# From 1989 onwards the rules are as follows:
#
# 1. Daylight Savings Time commences midnight of the first Saturday night
#    following the seven-day festival of Pesach (Passover).  The transition
#    is from midnight Israel Standard Time to 1 a.m. Israel Daylight Savings
#    time.  As the Pesach festival is dependent on the Lunar calendar (the
#    first day is always on the 15th day of the month of Nisan), the rule
#    changes every year on the Gregorian calendar.
#
# 2. Standard Time is reinstated on the Saturday night whereupon Jews
#    following the Ashkenazi (European) rite begin to recite the Selichot
#    (forgiveness) prayers prior to the Jewish Lunar New Year.  The transition
#    is from midnight Israel Daylight Savings time to 11 p.m. Israel Standard
#    Time.  The law (according to the Ashkenazi custom) concerning the
#    commencement of the Selichot prayers is described in chapter 128, section
#    5 of the "Code of Jewish Law," by Rabbi Shlomo Ganzfried (translated by
#    Hyman E. Goldin):
#
#       Beginning with the Sunday [**] before Rosh Hashanah [***],
#       we rise early for the service of Selichot (supplications for
#       forgiveness).  If Rosh Hashanah occurs on Monday or Tuesday, we
#       begin saying the Selichot from the Sunday of the preceding week.
#
#    This, too, varies from year to year on the Gregorian calendar and, thus,
#    two explicit timezone rules are required for each Gregorian year.
#
#    [**] actually Saturday night as the Jewish day commences at nightfall.
#    [***] the Jewish Lunar New Year.
