Changes in Israel's 1997 Daylight Savings Rules

Yesterday, the Knesset (Israeli parliament) passed a law changing the
daylight savings changeover times for 1997 (a mere ten days from when the
old times were to take effect).

Attached is the new Zic file for Israel with the corrected 1997 times.  For
now, the times for 1998 remain the same and there are no official times for
1999 and on.  Please note that I have altered some of the comments as well.

The official announcement (in Hebrew) is in the gzipped postscript file:

An article from the English-language Jerusalem Post of late January explains
the rational for the change and can be found in:

Please note that the starting time mentioned in the English-language article
is NOT the time that was finally decided upon by the Knesset.

# According to the Office of the Secretary General of the Ministry of
# Interior, there is NO set rule for Daylight-Savings/Standard time changes.
# Each year they decide anew what havoc to wreak on the country.  However,
# there is a "supposed" set of rules which is subject to change depending
# on the party the Minister of Interior, the size of the coalition
# government, the phase of the moon and the direction of the wind.  Hence,
# changes may need to be made on a semi-annual basis.  One thing is entrenched
# in law, however: that there must be at least 150 days of daylight savings
# time annually.  The change to daylight savings time is from midnight IST
# to 1 a.m IDT (day of week varies in different years).  The change back to
# standard time is on a Saturday night from midnight daylight savings time
# to 11 p.m. standard time.  1996 is an exception to this rule where the
# change back to standard time took place on Sunday night instead of Saturday
# night to avoid conflicts with the Jewish New Year.
