[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

Re: [tz] Proposal to revert 2023b's Lebanon data changes
by Ahmad SOLH March 28, 2023

March 28, 2023

Dear, We understand that you may have received numerous emails regarding the recent Lebanon daylight saving and unplanned government decisions. As business owners and professionals, we respectfully request that you consider reverting to the previous summer time settings, especially since the government has withdrawn their decision effective 30th of March. Continuing with the newly implemented changes may negatively impact our businesses and cause us to fall out of sync with the rest of the world. We sincerely apologize on behalf of our government and believe that the actions of our leaders should not have an adverse effect on the people. Thank you, Regards, Ahmad SOLH Managing Director [cid:em15232572-152b-45b6-84f4-be0601b0fbc8@5c84fd39.com] M (CA) : +1-514-400 2490 | M (DxB) : +971-56-157 7898 | M (LB) : +961-3-414 664 CA: 292F Dalehurst Dr, Nepean, K2G 4E4, ON, Canada UAE: 2708, Sama Tower, World Trade Center, Dubai, UAE --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Disclaimer: This email may contain confidential information intended for the person or organization to which it is addressed.

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

Thank you!

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. Thank you! |---------------------------------------------------------------------| | Frederick F.
