I.e., either Ephraim Silverberg, who contributed the most-recently-seen rules
for Israel, as seen in "/usr/share/lib/zoneinfo/asia" in SunOS 4.x and
5.x systems and elsewhere:
# 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.
was mistaken, or, after he sent that information out, the government
went back to changing the rules every year?
