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. !

Syntax highlighting for Sublime Text
by Gilmore Davidson Aug. 16, 2017

Aug. 16, 2017

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

Proposal: validation text file with releases
by Jon Skeet Dec. 19, 2016

Dec. 19, 2016

Background: I'm the primary developer for Noda Time <http://nodatime.org> which consumes the tz data. I'm currently refactoring the code to do this... and I've come across some code (originally ported from Joda Time) which I now understand in terms of what it's doing, but not exactly why. For a little while now, the Noda Time source repo has included a text dump file <https://github.com/nodatime/nodatime/blob/master/src/NodaTime.Test/TestData…>, containing a text dump of every transition (up to 2100, at the moment) for every time zone. It looks like this, picking just one example: Zone: Africa/Maseru LMT: [StartOfTime, 1892-02-07T22:08:00Z) +01:52 (+00) SAST: [1892-02-07T22:08:00Z, 1903-02-28T22:30:00Z) +01:30 (+00) SAST: [1903-02-28T22:30:00Z, 1942-09-20T00:00:00Z) +02 (+00) SAST: [1942-09-20T00:00:00Z, 1943-03-20T23:00:00Z) +03 (+01) SAST: [1943-03-20T23:00:00Z, 1943-09-19T00:00:00Z) +02 (+00) SAST: [1943-09-19T00:00:00Z, 1944-03-18T23:00:00Z) +03 (+01) SAST: [1944-03-18T23:00:00Z, EndOfTime) +02 (+00) I use this file for confidence when refactoring my time zone handling code - if the new code comes up with the same set of transitions as the old code, it's probably okay. (This is just one line of defence, of course - there are unit tests, though not as many as I'd like.) It strikes me that having a similar file (I'm not wedded to the format, but it should have all the same information, one way or another) released alongside the main data files would be really handy for *all* implementors - it would be a good way of validating consistency across multiple platforms, with the release data being canonical. For any platforms which didn't want to actually consume the rules as rules, but just wanted a list of transitions, it could even effectively replace their use of the data. One other benefit: diffing the dump between two releases would make it clear what had changed in *effect*, rather than just in terms of rules. One sticking point is size. The current file for Noda Time is about 4MB, although it zips down to about 300K. Some thoughts around this: - We wouldn't need to distribute it in the same file as the data - just as we have data and code file, there could be a "textdump" file or whatever we'd want to call it. These could be retroactively generated for previous releases, too. - As you can see, there's redundancy in the format above, in that it's a list of "zone intervals" (as I call them in Noda Time) rather than a list of transitions - the end of each interval is always the start of the next interval. - For zones which settle into an infinite daylight saving pattern, I currently generate from the start of time to 2100 (and then a single zone interval for the end of time as Noda Time understands it; we'd need to work out what form that would take, if any). If we decided that "year of release + 30 years" was enough, that would cut down the size considerably. Any thoughts? If the feeling is broadly positive, the next step would be to nail down the text format, then find a willing victim/volunteer to write the C code. (You really don't want me writing C...) Jon

zic changes (2/2)
by Arthur David Olson March 9, 2016

March 9, 2016

And now, the update. These changes arrange things so that binary files include "transition" entries for minimum time values; these entries eliminate localtime guesswork in handling low-valued time stamps. The bad news: binary files grow slightly as a result of these changes. The good news: there are no changes in the output of "zdump -v" applied to before-and-after versions of all the binary files generated by a "make install." Changes are attached and appear in mangled form below; these are relative to the github version of zic.c after the rollback in the earlier message today. @dashdashado 1.2 2805 lines 1.4 2813 lines *** /tmp/,azic.c 2014-05-01 01:51:36.998933800 -0400 --- /tmp/,bzic.c 2014-05-01 01:51:37.092534000 -0400 *************** *** 1480,1493 **** fromi = 0; while (fromi < timecnt && attypes[fromi].at < min_time) ++fromi; - if (isdsts[0] == 0) - while (fromi < timecnt && attypes[fromi].type == 0) - ++fromi; /* handled by default rule */ for ( ; fromi < timecnt; ++fromi) { ! if (toi != 0 && ((attypes[fromi].at + gmtoffs[attypes[toi - 1].type]) <= !

7 regions in Russia submitted draft bills to change their time zones
by Alexander Krivenyshev Feb. 18, 2016

Feb. 18, 2016

After researching several official government documents (duma.gov.ru), there are at least 7 regions in Russia (not 3) that have submitted draft bills proposing changes to their time zones. Those regions are: - Zabaykalsky Krai / Chita (draft bill date of entry July 16, 2015)- has recently received approval to change time zone from UTC+8 to UTC+9 - Astrakhan Oblast / Astrakhan (draft bill date of entry Aug. 15, 2015), UTC+3 to UTC+4 - Sakhalin Oblast / Yuzhno-Sakhalinsk (draft bill date of entry Sep. 28, 2015), UTC+10 to UTC+11 - Ulyanovsk Oblast / Ulyanovsk (draft bill date of entry Nov. 03, 2015), UTC+3 to UTC+4 - Altai republic / Gorno-Altaysk (draft bill date of entry Nov. 23, 2015), UTC+6 to UTC+7 - Altai Krai / Barnaul (draft bill date of entry Dec. 03, 2015), UTC+6 to UTC+7 - Magadan Oblast / Magadan (draft bill date of entry Dec. 08, 2015), UTC+10 to UTC+11 See as a reference Russia map with 7 regions to change their time zones (darker colors of blue, green, red): http://www.worldtimezone.com/russia-time-zones-map-2016-04.gif (vs current http://www.worldtimezone.com/time-russia12.php) Seems that draft bill in Russia must pass through the following phases before being signed into law: Phase 1- The State Duma Council draft bill review Phase 2- Pass three (3) readings/revisions by the State Duma Phase 3- Approval by the Federation Council Phase 4- Signed by the President. Currently there are 6 additional regions in Russia that have requested to change their time zones (make amendments to the current Federal Law "On the calculation of time"), those draft bills were introduced at different times and are in different phases of the approval (or rejection) process. To make it easier to understand, below are the approximate phases of the remaining regions requesting time zones changes: - Sakhalin Oblast / Yuzhno-Sakhalinsk - Phase 1 (introduced to the State Duma Council) - Astrakhan Oblast / Astrakhan - Phase 2 ( first reading by the State Duma) - Ulyanovsk Oblast / Ulyanovsk - Phase 1 (introduced to the State Duma Council) - Altai republic / Gorno-Altaysk - Phase 1 (introduced to the State Duma Council) - Altai Krai / Barnaul - Phase 1 (introduced to the State Duma Council) - Magadan Oblast / Magadan - Phase 1 ( introduced to the Chairman of the State Duma- part of the State Duma Council) It is hard to say, how many above regions will be able to get through all these phases and change their time zones by March 27, 2016. We will try to keep our eyes on it. Alexander Krivenyshev http://www.worldtimezone.com

[PATCH 1/3] zone*.tab: make consistent 'most locations'
by J William Piggott Feb. 13, 2016

Feb. 13, 2016

modified: zone.tab modified: zone1970.tab The comments (field 4) inconsistently use leading area names. This causes tzselect's output to be mixed: Please select one of the following time zone regions. 1) Buenos Aires (BA, CF) 2) most locations (CB, CC, CN, ER, FM, MN, SE, SF) Please select one of the following time zone regions. 1) Lord Howe Island 2) Macquarie Island 3) Tasmania - most locations The leading name is absent from entries when it would match the chosen country, but sometimes the chosen country is no longer visible. Including the country name doesn't hurt anything and it improves readability.
