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?
