+# Georgia moved closer to Western Europe on Sunday...  The former Soviet
+# republic has changed its time zone back to that of Moscow.  As a result it

+# (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
