I agree. If Brazil changes its mind again this year, we can issue a
new version then.
Here's a proposed patch to the tz data that incorporates our
discussion about Brazil, along with some other lower-priority patches
that I had saved up.
* Changes to current or future data.
- In Brazil DST starts the 3rd Sunday in October this year, and BA,
MT and TO no longer observe DST. New Zones America/Bahia and
America/Campo_Grande. Thanks to Paulo Alexandre Pinto Pires for
the details.
* Changes to historical data.
- In Canada, fix many transitions before 1960. New entry America/Toronto,
which the backwards-compatibility entry Canada/Eastern links to.
- In Asia/Aqtau, the 1995 switch from 5:00 to 4:00 was Mar, not Sep.
- Pacific/Chatham was 45 minutes ahead of Pacific/Auckland
from 1947 to 1990.
- For Pacific/Auckland, change many transitions before 1947, by using
data from the Department of Internal Affairs and Carol Squires in
preference to Shanks. Standard time was called "Mean Time"
and daylight-saving time was called "Summer Time" before 1947.
- Pacific/Midway observed DST in 1956.
- Use abbreviations like "EPT" for Eastern Peace Time in
non-US American locations, too.
- Lisbon introduced standard time on January 1, 1912, not May 24, 1911.
* Changes to non-timezone data.
- Serbia & Montenegro's country code has changed from YU to CS.
- Change descriptions for America/Sao_Paulo, America/Cuiaba,
America/Montreal reflecting their new, smaller locations.
Fix typo in America/Fortaleza description.
- Fix latitude and longitude of Pacific/Chatham.
* Commentary fixes.
- Update comments about Israel; thanks to Ephraim Silverberg.
- Describe Brazilian time zone borders more accurately; thanks
to Oscar van Vlijmen.
- Add comments by Mark Brader about early DST in Canada.
- Add more commentary about William Willett, including a 1934 paean
to Willett by Winston Churchill.
- Add somewhat-confused claim that Wake Island observed double-DST
in 1950.
* Changes to tz-link.htm web page.
- Add references to Mac OS X, OpenVMS.
- XCal seems to be dead; cut down on its description and
talk about it in the past tense.
- webexhibits.com -> webexhibits.org.
- Revert Australian link back to the NSW AG office,
since www.dstc.qut.edu.au/DST/marg seems to be down.
- Adjust link to history of DST in Chile, to point to WebExhibits,
since the SHOA no longer seems to publish it.
- Add references to Carol Squires's New Zealand page,
to Steve Allen's leap second issue catalog, and
to the Nelson et al. paper about abolishing leap seconds.
- Update links to PTB, IERS, Leap Second Discussion List, Yahoo.

-# The Israeli government today adopted a proposal by Minister of Interior
-# Eli Yishai to shorten the period of Daylight Savings Time for the year
-# 2002 (only -- the dates for 2003 and 2004 are, so far, unaffected).
-#
-# The proposed date to Daylight Savings Time is September 13, 2002 instead
-# of the current date: October 7, 2002. The hour of changeover has not
-# yet been decided.
-#
-# (2002-07-10):
-# While today the Knesset passed the initial proposal to reduce DST by
-# some three weeks, a new compromise is being worked out between
-# Minister of Justice Meir Sheetrit and Minister of Interior Eli
-# Yishai to revert to standard time for a period of 48-96 _hours_
-# (sic) around the Yom Kippur fast day (September 15-16) and then go
-# *back* to DST until the end of October. The details of the proposal
-# have yet to be worked out, but the second and final readings of the
-# bill have until July 24 to pass.

-# Thanks go to Yitschak Goldberg from E&M for bringing this (Hebrew) article
-# to my attention:
-#
-# http://www.ynet.co.il/articles/0,7340,L-2019315,00.html
-#
-# Hence, the proposal to shorten DST was withdrawn yesterday and the timezone
-# files that have been in effect since July 2000 are still valid for all of
-# 2002.
-#
-# Please note that the article mentions that the Shas MK's intend to
-# bring up their amendment for future years (2003 and beyond). What this
-# means exactly is anyone's guess since there are no set dates yet beyond
-# 2004 and the end day set for 2003 and 2004 is already the 7th of Tishrei
-# (i.e. before the fast of Yom Kippur). The only thing they may want to
-# change is the start date of DST in 2003 from Mar.28.03 (24th of Adar II)
-# to Apr.18.03 (16th of Nisan) so that the Passover Seder will take place
-# during Standard Time. The start date for 2004 is already Nisan 16th.
+# 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
