The sooner tzdata is updated the more likely it is that changes be deployed in time, and perhaps even included in new releases of the different operating systems that uses tz.
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. =================================================================== RCS file: RCS/asia,v retrieving revision 2003.1 retrieving revision 2003.1.0.1 diff -pu -r2003.1 -r2003.1.0.1 --- asia 2003/03/24 14:30:54 2003.1 +++ asia 2003/09/20 08:54:30 2003.1.0.1 @@ -736,44 +736,19 @@ Zone Asia/Jerusalem 2:20:56 - LMT 1880 2:20:40 - JMT 1918 # Jerusalem Mean Time? 2:00 Zion I%sT -# From Ephraim Silverberg (2002-07-07): +# From Ephraim Silverberg (2003-03-23): # -# 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.
