proposed time zone package changes (Samoa, Factory, et al.)
by Arthur David Olson Aug. 28, 2019

Aug. 28, 2019

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. !

proposed tz change for Latvia, Lithuania

Adding Asia/Beijing timezone into the database
by Daoming Qiu Dec. 6, 2014

Dec. 6, 2014

"Beijing Time" is the standard time used for China region, so it is very strange that tzdatabase doesn't have timezone called Asia/Beijing. Strongly suggest to add "Asia/Beijing" zone into the database, and its information is very similar with "Asia/Shanghai".

a patch for zic.c to allow 'follow rules'
by Alois Treindl Sept. 10, 2013

Sept. 10, 2013

Dear Arthur, I have been preparing a small modification for zic.c which will allow it to understand a 'follow rule' in zone files, like this: # experimental table for Geneva, to test the 'follow' mechanism Zone Europe/Geneva 0:24:37 - LMT 1848 Sep 12 0:24:37 - GET 1894 Jun # Geneva MTime 0 follow Europe/Zurich For test purposes, one can simply insert this zone in the europe file. The feature is helpful in the extension of tzdata to cover complete timezone history. For this purpose, about 1000 additional zone files need to be written, and to be maintained. The process to do so has started in the astrological community, as it needs a complete pre-1970 timezone history. I will not bother you with details. I intend to help creating and maintaining a set of files like 'europe_hist', 'asia_hist' etc which contain the additional zones. The 'follow rule' will allow to keep these extra zone files very small, as usually the additional zones will all have a cross-over moment into a regular tzdata zone. I have for the moment called the modified zic source file zicx.c and prepared a patch file for zic.c to implement the 'follow rule' feature. I have tried to keep the modification very small. Please have a look at the patch, and check for the errors I have probably made. Description of the code: ------------------------ The follow rule must be the last line in a zone, and recursion is not allowed. It is parsed in inzsub() which reacts on GMTOFF = 0 and the word 'follow' in the RULE field. The zone line is stored in zones[] with a special value z_gmtoff = FOLLOW_MARK and the zone_name to follow in field z_rule (which is abused for this purpose). Before the call to outzone() the two sets of zone lines are patched together in a temporary array, so that outzone() and all functions deeper down() need not be modified.

Australia AEDT/EDT
by Steven Weiss Nov. 1, 2012

Nov. 1, 2012

Hi, I've been testing the timezone abbreviation and it seems to be incorrect for the current DST The abbreviation is giving me a EST instead of the expected EDT. I'm aware from your list there is a lot of discussion around EST/EDT vs AEST/AEDT. This is not the issue for me. either/or would be fine. Rather it appears that it should currently EDT/AEDT. I've downloaded the latest data and code as per the README. Regards Steven Weiss Cape Town South Africa

[PATCH 1/3] build: handle standard LDFLAGS variable
by Mike Frysinger Oct. 28, 2012

Oct. 28, 2012

This changes LFLAGS to the more standard LDFLAGS (while preserving backwards compatibility). It also adds the missing $(LDFLAGS) usage when linking `date`.

[I forgot to CC: this to tz(a)iana.org, so I am doing it separately this time.] -------- Original Message -------- Subject: tzcode2012h and tzdata2012h available Date: Fri, 26 Oct 2012 23:18:24 -0700 From: Paul Eggert <eggert(a)cs.ucla.edu> To: Time zone announcements <tz-announce(a)iana.org> The 2012h release of the tz code and data is available. It reflects the following changes recently circulated on the tz mailing list: Bahia no longer has DST. (Thanks to Kelley Cook.) Tocantins has DST. (Thanks to Rodrigo Severo.) Israel has new DST rules next year. (Thanks to Ephraim Silverberg.) Jordan stays on DST this winter. (Thanks to Steffen Thorsen.) Web page updates. More C modernization, except that at Arthur David Olson's suggestion the instances of 'register' were kept.

Australian Timezone Abreviations - Next step
by Shaun Bouckaert Oct. 26, 2012

Oct. 26, 2012

After taking some time off from this issue, I've considered the next logical step to be contacting the relevant government departments in charge of the timezone legislation in each state. As a Queenslander I will start with the Queensland Attorney-General, as the timezone legislation falls under his responsibility. I honestly believe that the only argument for the status quo on this issue is that it's been this way for a long time. I have previously presented many good arguments as to why it needs to be updated to reflect what is widely used amongst government and private organisations across the country, and what is presented by the federal government on this page http://australia.gov.au/about-australia/our-country/time Hopefully, with responses from the relevant state departments, this issue can be resolved and put to bed.
