-# From Ephraim Silverberg (2003-03-23):
-#
-# Minister of Interior Poraz has announced that he will respect the law
-# passed in July 2000 (proposed at the time jointly by himself and
-# then-MK David Azulai [Shas]) fixing the dates for 2000-2004. Hence,
-# the dates for 2003 and 2004 remain unchanged....
-#
-# As far as 2005 and beyond, no dates have been set. However, the
-# minister has mentioned that he wishes to propose to move Israel's
-# timezone in 2005 from GMT+2 to GMT+3 and upon that have DST during
-# the summer months (i.e. GMT+4). However, no legislation in this
-# direction is expected until the latter part of 2004 which is a long
-# time off in terms of Israeli politics.
-
-# (2004-09-20):
-# The latest rumour, however, is that in 2005, when the clock changes to
-# Daylight Saving Time (date as yet unknown), the move will be a two-hour leap
-# forward (from UTC+0200 to UTC+0400) and then, in the fall, the clock will
-# move back only an hour to UTC+0300 thus effectively moving Israel's timezone
-# from UTC+0200 to UTC+0300. However, no actual draft has been put before the
-# Knesset (Israel's Parliament) though the intention is to do so this
-# month [2004-09].
-
-# (2004-09-26):
-# Even though the draft law for the above did pass the Ministerial Committee
-# for Legislative Matters three months ago, it was voted down in today's
-# Cabinet meeting. The current suggestion is to keep the current timezone at
-# UTC+0200 but have an extended period of Daylight Saving Time (UTC+0300) from
-# the beginning of Passover holiday in the spring to after the Tabernacle
-# holiday in the fall (i.e. the dates of which are governed by the Hebrew
-# calendar but this means at least 184 days of DST). However, this is only a
-# suggestion that was raised in today's cabinet meeting and has not yet been
-# drafted.
