proposed time zone package changes (Samoa, Factory, et al.)
by Arthur David Olson 28 Aug '19

28 Aug '19

Below find proposed time zone package changes; the executive summary: * Makefile Change LOCALTIME default from "Factory" to "GMT"; do not compile "factory" file (but keep it in the distribution). * Theory Remove reference to "Factory" zone. * australasia Change end of DST in Samoa in 2011 from 2011-04-03 0:00 to 2011-04-03 1:00 (thanks to Raymond Hughes for a reference). * localtime.c Initialize ttinfo structures filled by tzparse (thanks to Ravindra for reporting a valgrind warning). * zic.c Fix generation of POSIX strings for zones with rules using "weekday<=n" forms of dates (thanks to Lei Liu for finding the problem). Also, limit output for non-POSIX-specificable zones defined to follow the same rules every year. (Note that no zones of either of the above types appear in the distribution; these changes cater to add-on zones). If no problems are found, 2010n will appear on 2010-10-25. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Mon Sep 27 09:24:25 2010 --- new/Makefile Tue Oct 12 12:36:50 2010 *************** *** 1,5 **** # <pre> ! # @(#)Makefile 8.8 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)Makefile 8.9 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 12,18 **** # make zonenames # to get a list of the values you can use for LOCALTIME. !

Alberta Tory leadership candidate petitions to drop DST and move to CT
by Brian Inglis 19 Sep '17

19 Sep '17

On the final day of the fall sitting on Tuesday, Alberta Progressive Conservative leadership candidate, Vermilion-Lloydminster MLA Richard Starke presented a petition to the legislature calling for repeal of the Daylight Saving Time Act and a move to Central Time (from Mountain Time), to be decided by a referendum. The stories linked below are all from the same news org and under the same byline. The latter two have a vote button at the bottom to poll readers' opinions, each currently running about 80/20 in favour of dropping DST, and/or possibly also of switching to permanent CT, depending on whether the voters read the question or just clicked. http://calgaryherald.com/news/politics/pc-leadership-candidate-starke-calls… http://www.edmontonjournal.com/news/politics/leadership+candidate+starke+ca… http://www.calgarysun.com/2016/12/14/to-keep-or-ditch-daylight-saving-time-… http://www.edmontonsun.com/2016/12/14/to-keep-or-ditch-daylight-saving-time… -- Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada

Syntax highlighting for Sublime Text
by Gilmore Davidson 16 Aug '17

16 Aug '17

Hi, I’ve created some tzdata syntax highlighting rules for the Sublime Text editor: https://packagecontrol.io/packages/zoneinfo <https://packagecontrol.io/packages/zoneinfo> I have no idea if anyone other than me uses that particular text editor for looking at tzdata files. But I thought I’d mention it just in case it’s useful to someone. Cheers, Gil

zone.tab / zone1970.tab inconsistency for TF/UM/VN
by Neil Fuller 03 Apr '17

03 Apr '17

This may be a misunderstanding on my part about the file formats of zone.tab and zone1970.tab and how consistent they are expected to be. I expect the exact zone IDs to be different, but there are only a few cases where countries differ in the number of referenced zone IDs. I realize that zone.tab is intended for backward compatibility but it looks like it is being well maintained. Is this difference expected? If it is, can somebody explain? Details below the line. Thanks for all the hard work.

[tz-announce] 2017b release of tz code and data available
by Paul Eggert 23 Mar '17

23 Mar '17

The 2017b release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Briefly: Haiti has resumed DST. Changes to past and future time stamps Haiti resumed observance of DST in 2017. (Thanks to Steffen Thorsen.) Changes to past time stamps Liberia changed from -004430 to +00 on 1972-01-07, not 1972-05-01. Use "MMT" to abbreviate Liberia's time zone before 1972, as "-004430" is one byte over the POSIX limit. (Problem reported by Derick Rethans.)

When did the subdirectory decision get made?
by Matthew Donadio 19 Mar '17

19 Mar '17

The northamerica file has this note in it: # From Paul Eggert (2007-08-17): # ... # 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'. I have gone through the mailing list archives from around this time, and also the 8/2005 timeframe (when the Indiana changes were starting to become clear), but I can't find any discussion about this, and Google is failing me. Does anyone remember when the pros and cons of using three levels for names was discussed? I just want to read up on some of that background. Thanks. --Matthew Donadio (matt(a)mxd120.com)
