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. - ############################################################################### diff --git a/timezone/backward b/timezone/backward index 6e118c2726..9fbab94d79 100644 --- a/timezone/backward +++ b/timezone/backward @@ -1,4 +1,4 @@ -# @(#)backward 7.26 +# @(#)backward 7.27 # This file provides links between current names for time zones # and their old names.
