Web sites using recent versions of the tz database
by Sylvia May 10, 2023

May 10, 2023

Dear team, My name is Silvia, I am the webmaster responsible for carta-natal.es. This is an astrology website wich uses the latest version of the TZ database for calculating astral charts with the correct UT hour and date. It includes a section where you can see the timezone details and time changes of each town throughout history: https://carta-natal.es/zona_horaria.php https://carta-natal.es/cambios_horarios.php Of course there could be some (mine/human) error in associating a time zone identifier to each locality. Do you think it would be possible and/or useful to add carta-natal.es to the web sites list at https://carta-natal.es/cambios_horarios.php? Thank you very much. kind regards, Silvia

More prominent/consistent record of rule change notification date?
by Jan Harris May 8, 2023

May 8, 2023

Greetings I deal with getting the TZ updates rolled out for IBM AIX. As we all know, sometimes IANA is notified in the eleventh hour, and it is not feasible for AIX to deliver fixes in a matter of weeks (or less) Take Egypt, for example. For good reason, IANA did initiate a new build on March 1, as discussed in this thread<https://mm.icann.org/pipermail/tz/2023-March/032683.html>. (Even if they did, it would have been a tight schedule for AIX to have ready mid April.) I certainly appreciate the emphasis on notifications, placed in the IANA article. How Time Zones Are Coordinated<https://www.icann.org/en/blogs/details/how-time-zones-are-coordinated-13-03…> * https://www.icann.org/en/blogs/details/how-time-zones-are-coordinated-13-03… I have incorporated this message in to our AIX TZ documentation. We usually see some attribution to the notification in the NEWS Starting in 2023, Egypt will observe DST from April's last Friday through October's last Thursday. (Thanks to Ahmad ElDardiry.) Assume the transition times are 00:00 and 24:00, respectively. I think it would be helpful if there was a clear record of WHEN IANA is officially notified of TZ changes, so users could understand this is the result of their government changes, and notification processes, it is not a "defect" in how IANA or vendors roll out these updates. I do realize that sometimes “official” notifications seems to be that someone submitted a more formal government reference, instead of a news article. Maybe just an indicator of when the group is provided such official confirmation. Thanks for your consideration!

Inconsistencies between backward and backzone
by Benjamin Drung May 4, 2023

May 4, 2023

Hi, building tz with PACKRATDATA=backzone should result in time zones that only differ for dates before 1970. For dates after 1970 they should be identical to not building with PACKRATDATA=backzone (using backzone to create symlinks). But there are four (five if you include Pacific/Enderbury) time zones that has different UTC offset nowadays: * America/Ensenada differs from America/Tijuana * Asia/Kashgar differs from Asia/Urumqi * Atlantic/Jan_Mayen differs from Europe/Berlin * Europe/Tiraspol differs from Europe/Chisinau First investigation indicate that the timezones in backzone did not get the recent updates applied to them. -- Benjamin Drung Debian & Ubuntu Developer

Introduce Etc/UTC+x timezones?
by Benjamin Drung May 4, 2023

May 4, 2023

Hi, If people are aware of timezones, they often know UTC and their offsets (e.g. Europe/Berlin is UTC+2 summer). But they are probably not aware that the Etc/GMT offsets are inverted (e.g. you have to select Etc/GMT-2 for UTC+2). I was not aware of that and other people as well as the bugs in Ubuntu and Debian indicate (see https://launchpad.net/bugs/1325949 and https://bugs.debian.org/540305) What do you think about the idea of introducing Etc/UTC+x timezones that have the "correct" offset so that people can select fixed offsets more easily? So Etc/GMT-2 would be renamed to Etc/UTC+2 and Etc/GMT-2 would become a symlink to it (same for all other Etc/GMT+x and Etc/GMT-x timezones). -- Benjamin Drung Debian & Ubuntu Developer

offtime_r
by Dag-Erling Smørgrav April 26, 2023

April 26, 2023

The tzcode distribution includes a (non-standard and undocumented) offtime() function but no offtime_r() function, which seems like an oversight. The attached patch (relative to 2023c) adds it. Regards, Dag-Erling

Mexico timezones
by Var Nazari April 10, 2023

April 10, 2023

Hello, Mexico has recently abolished daylight savings except for where they border with the United States. I believe the timezone database is now inaccurate because it should not be showing CDT for most of the country any longer and should be CST instead. It seems like this was addressed in release notes for the tzdb version 2022f and 2022g but I'm not sure that the correct changes were applied. Could you verify/explain why the timezones in Mexico are still recorded as CDT? Is this a mistake? Thank you

Changing 24:00 to 0:00 where possible
by Jacob Pratt April 5, 2023

April 5, 2023

While writing a parser for tzdb files, I noticed that some rules are for a given date at 24:00, rather than the following day at 0:00. While in some cases this is unavoidable (Egypt), in others there is no reason this is necessary (Belize). I think it would be reasonable to change 24:00 to 0:00 where possible, incrementing the day, day of week, and month as appropriate. This would reduce the need for special casing values to those that have a technical reason. Jacob Pratt

Error in the "America/Santiago" timezone for one week of September 2022
by Javier Ayala March 31, 2023

March 31, 2023

Hello, There is an error in the 'America/Santiago' timezone. The week between September 4th, 2022 and September 10th, 2022 should have the offset of -4.0, but it currently shows -3.0. This error occurred due to the 2022 Chilean national plebiscite <https://en.wikipedia.org/wiki/2022_Chilean_national_plebiscite>, which caused the government to postpone the scheduled time change by one week, from September 3rd to September 10th. Sources: - Decree in Chile's Official Gazette: https://www.diariooficial.interior.gob.cl/publicaciones/2022/08/13/43327/01… - News published in Chile's government website: https://www.gob.cl/noticias/ministerio-del-interior-informa-respecto-al-cam… Greetings, Javier Ayala

Re: [tz] [PROPOSED 2/2] Fix comments on Lebanon this week
by Paige Tummons March 29, 2023

March 29, 2023

Hi Paul, I'm reaching out regarding your request for comments<https://mm.icann.org/pipermail/tz/2023-March/032833.html> on the proposal to revert back to 2023a instead of updating 2023c to reflect the Lebanon DST change of 30 March. I've been working closely with medical centers in Lebanon to ensure that their healthcare systems are in continuous legal compliance with the government directives. We have been in close communication with Lebanese government authorities who legally consider the spring forward event to be on 30 March (with the jump being from 11:59:59 PM on 29 March to 01:00:00 AM on 30 March). We are strongly urging you to reflect this update in the 2023c file, to avoid the published tzdata file being in direct conflict with the government directive of the spring DST event in Lebanon happening on 30 March. The Prime Minister met with the cabinet yesterday, and together they agreed that Lebanon DST happens on the 30th of March. No government authorities consider the 26 March 2023 event to be the "true" DST time for Lebanon. Thanks, Paige Tummons

[tz-announce] 2023c release of tz code and data available
by Paul Eggert via tz-announce March 28, 2023

March 28, 2023

The 2023c release of the tz code and data is available. This release's code and data are identical to 2023a. In other words, this release reverts all changes made in 2023b other than commentary, as that appears to be the best of a bad set of short-notice choices for modeling this week's daylight saving chaos in Lebanon. (Thanks to Rany Hany for the heads-up about the government's announcement this week.) Here are links to the release files: https://www.iana.org/time-zones/repository/releases/tzcode2023c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdata2023c.tar.gz https://www.iana.org/time-zones/repository/releases/tzdb-2023c.tar.lz The following convenience links are also available, although they may point to the previous release until the relevant caches are refreshed: https://www.iana.org/time-zones/repository/tzcode-latest.tar.gz https://www.iana.org/time-zones/repository/tzdata-latest.tar.gz https://www.iana.org/time-zones/repository/tzdb-latest.tar.lz Links are also available via plain HTTP, and via FTP from ftp://ftp.iana.org/tz/releases with the same basenames as above. Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs. Copies of these signatures are appended to this message. This release corresponds to commit ddb8cf09d54ecc486ed6665edcdd642abccd4eef dated 2023-03-28 12:42:14 -0700 and tagged '2023c' in the development GitHub repository at <https://github.com/eggert/tz>.

Policy Suggestion: Minimum time period betwen releases
by Howard Hinnant March 28, 2023

March 28, 2023

Recent events have brought to my attention the need to put a damper on chaos caused by poor planning. When governments give little notice to changes in time zone rules, this is not a problem that this group can fix, or should even try. I propose a minimum period of 30 days between successive IANA tz database releases. The train leaves the station no more frequently than once every 30 days (and will probably be less frequent). Whatever information is solid before the release date makes it on the train. Otherwise it can wait another 30 days (at least). My recommendation is in part based on this common statement: Poor planning on your part does not constitute an emergency on my part https://www.incirlik.af.mil/News/Commentaries/Display/Article/303134/poor-p… This week’s chaos isn’t unusual. In fact it is normal, especially for some countries. If they can’t be bothered to make a plan in advance and stick with it, I don’t see why this group of volunteers needs to compensate for that. Let the politicians lie in the beds they make. Howard

Apple pushing out 2023b
by Jad Baz March 28, 2023

March 28, 2023

It seems Apple is pushing out 2023b A survey on a Lebanese Telegram group shows that iOS users are receiving a notification to restart their devices to apply timezone changes This seems to be an incrmental rollout, however, as not all users have reported getting a notification Some MacBook users have also reported receiving a similar notification I checked with both iOS and MacBook users asking them to restart their laptop, set the date/time to April 20th at 23:59 and within a minute, it sprung forward to April 21st at 01:00 So this is undoubtedly 2023b and nothing else

As someone who mostly just _uses_ the TZ database to support various projects, I’d like to take a short break in our current Mideast Moment to express my gratitude to all of those volunteers who work to keep this oft-overlooked but critical bit of IT infrastructure accurate and functional. This includes both those who work on the code and data directly as well as the researchers and others “on the ground” who keep this group informed in the midst of sometimes chaotic and fast-moving situations. I greatly appreciate the time, effort and professionalism that all of you consistently bring to this task.

Proposal to revert 2023b’s Lebanon data changes
by Paul Eggert March 27, 2023

March 27, 2023

We need a new release soon to address the time zone chaos in Lebanon. One option is to revert 2023b's data and go back to 2023a as I suggested earlier. Another is to record the chaos in more detail in the data. The attached proposed patch (which I installed into the developmental repository on GitHub) takes the former approach, as I expect the latter would cause more problems than it would cure. This follows a similar (although not identical) precedent in Rio de Janeiro in 1993. In short, the patch would make 2023c identical to 2023a except for comments, which do not count as part of the data. It is a confusing and controversial situation. Comments welcome. In the meantime I again suggest to downstream distributors to stick with 2023a and avoid 2023b.

Thank you for the info about Lebanon deciding today to not change its clocks this weekend. Ouch, this is very short notice. Since the March 25 transition was scheduled for 24:00 (i.e., midnight between March 25 and March 26) I assume this means the spring forward transition is will occur midnight between April 20 and April 21. I created the attached proposed patch to record this. Please let me know if this interpretation sounds correct to you. We'll need a new tzdb release soon, as tzdb 2023a becomes wrong around 51 hours from now. >> On 23 Mar 2023, at 6:26 PM, Saadallah Itani <sitani(a)aub.edu.lb> wrote: >> >> Hello, >> >> Lebanon too announced today delay of Spring forward from March 25 to April 20. >> >> preview.jpeg >> 960008904374 >> <https://imagescdn.mtv.com.lb/articles/960008904374.jpg?width=2000&quality=75> >> JPEG Image · 19 KB >> <https://imagescdn.mtv.com.lb/articles/960008904374.jpg?width=2000&quality=75> >> >> <https://imagescdn.mtv.com.lb/articles/960008904374.jpg?width=2000&quality=75> >> >> >> Regards, >> Saad >> Ext. 2229 >> >> Sent from my iPhone
