520# changes may need to be made on a semi-annual basis. One thing is entrenched
521# in law, however: that there must be at least 150 days of daylight savings
522# time annually. Ever since 1993, the change to daylight savings time is
523# on a Thursday night from midnight IST to 1 a.m IDT. The change back to

525# to 11 p.m. standard time. 1996 is an exception to this rule where the
526# change back to standard time took place on Sunday night instead of Saturday
527# night to avoid conflicts with the Jewish New Year.

574# From Member of Knesset Avraham Poraz, as quoted in Ha'aretz (1998-09-02):
575# [The 1998-09-06 transition is to] serve the interests of a small minority
576# of ultra-Orthodox Sephardic Jews who, during the [Hebrew] month of Elul,
577# recite Slihot penitential prayers in the early morning hours
578# and thus find daylight time inconvenient.
583# Due to imminent elections in 1999, there are no dates for the year 2000
584# and beyond. There was a move to legislate the DST rules in Israel, but
585# due to the government's fall, it most likely won't be brought to the Knesset
586# for first reading before the elections and will probably be altered by the
587# newly elected government.

628
629# From Hideyuki Suzuki (1998-11-16):
630# The ordinance No. 51 (1886) established "standard time" in Japan,
631# which stands for the time on E 135 degree.
632# In the ordinance No. 167 (1895), "standard time" was renamed to "central
633# standard time". And the same ordinance also established "western standard
634# time", which stands for the time on E 120 degree.... But "western standard
635# time" was abolished in the ordinance No. 529 (1937). In the ordinance No.
636# 167, there is no mention regarding for what place western standard time is
637# standard....
638#
639# I wrote "ordinance" above, but I don't know how to translate.
640# In Japanese it's "chokurei", which means ordinance from emperor.
641
642# Shanks claims JST in use since 1896, and that a few places (e.g. Ishigaki)
