# 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.

# What time is it in Indiana?
# </a> (1999-04-06)
# </a> (2005-05-03)
#
# From Paul Eggert (2005-08-22):
# Since 1970, most of Indiana has been like America/Indiana/Indianapolis,
# with the following exceptions:
#
# - Gibson, Jasper, Lake, LaPorte, Newton, Porter, Posey, Spencer,
# Vandenburgh, and Warrick counties have been like America/Chicago.
#
# - Dearborn and Ohio counties have been like America/New_York.
#
# - Clark, Floyd, and Harrison counties have been like
# America/Kentucky/Louisville.
#
# - Crawford, Starke, and Switzerland counties have their own time zone
# histories as noted below.
#
# From Paul Eggert (1995-12-19):
# Indiana generally observes either EST all year, or CST/CDT,
# but areas near Cincinnati and Louisville use those cities' timekeeping
# and in 1969 and 1970 the whole state observed daylight time;
# and there are other exceptions as noted below.
# Shanks partitions Indiana into 345 regions, each with its own time history,
# and writes ``Even newspaper reports present contradictory information.''
# Fortunately, most of the complexity occurred before our cutoff date of 1970.
#
# Since 1970, EST-only Indiana has been like America/Indianapolis,
# with exceptions noted below for Crawford, Starke, and Switzerland counties.
# The parts of Indiana not listed below have been like America/Chicago,
# America/Louisville, or America/New_York.
#
# Other than Indianapolis, the Indiana place names are so nondescript
# that they would be ambiguous if we left them at the `America' level.
# So we reluctantly put them all in a subdirectory `America/Indiana'.
#
# Most of EST-only Indiana last observed DST in 1970.
# From Paul Eggert (2001-03-06), following a tip by Markus Kuhn:
# Pam Belluck reported in the New York Times (2001-01-31) that the
# Indiana Legislature is considering a bill to adopt DST statewide.
# Her article mentioned Vevay, whose post office observes a different
# time zone from Danner's Hardware across the street.
# From Paul Eggert (2005-08-16):
# http://www.mccsc.edu/time.html says that Indiana will use DST starting 2006,
# and that many counties may switch either to Central or to Eastern time.
# The county-by-county decisions have not been made yet, so for now assume
# that no counties will switch: this assumption is most likely wrong,
# but it's the best we can do for now.

# The northamerica file says that Nicaragua has been on UTC-6 continuously
