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.

Lebanon will not spring forward this weekend

Thank you for the info about Lebanon deciding today to not change its clocks this weekend. Ouch, this is very short notice.

Re: [tz] tz Digest, Vol 138, Issue 71

Though this list usually doesn't include discussion of the time-zone-rule data that Microsoft maintains in the Windows registry, it seems worth considering how to ensure the two repositories of time-zone rules might be kept in sync—not to mention IATA's repository. Thoughts and opinions from any MS representatives would be welcome. (Incidentally, I was born at 11:50 PM at a place and time when hospitals recorded births on standard time even though the general population observed DST. Consequently, I reserve the right to celebrate my birthday on the 12th and/or 13th of July.) ________________________________ From: tz <tz-bounces(a)iana.org> on behalf of tz-request(a)iana.org <tz-request(a)iana.org> Sent: Monday, March 27, 2023 1:29 PM To: tz(a)iana.org <tz(a)iana.org> Subject: tz Digest, Vol 138, Issue 71 Send tz mailing list submissions to tz(a)iana.org To subscribe or unsubscribe via the World Wide Web, visit https://na01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fmm.icann.o… or, via email, send a message with subject or body 'help' to tz-request(a)iana.org You can reach the person managing the list at tz-owner(a)iana.org When replying, please edit your Subject line so it is more specific than "Re: Contents of tz digest..."

Lebanese Time Zone

March 27, 2023

Hello, Your recent changes to Lebanon's adherence to DST is wrong: "This year Lebanon springs forward April 20/21 not March 25/26. (Thanks to Saadallah Itani.)" https://data.iana.org/time-zones/tzdb/NEWS The government of Lebanon did not issue a law decree stating this change and proper legal procedures were not followed. This led to civil action locally where all respected media and groups are not abiding by this decision, taken without any proper legal procedures. Please correct the change on your end to avoid adding to the massive confusion. All devices have already updated to DST, so your change is only adding to the confusion. Thank you for your understanding. I do not give the right to use my name, email or any other identifying information on any public communications or messages or updates.

Lebanon DST change reverted

Greetings, The DST change for Lebanon that was adopted in 2023b should be reverted 48 hours from now. The cabinet met today and rolled it back. The Council of Ministers decided to adopt daylight saving time once again starting from Wednesday night (needs details on exactly when "Wednesday night" is, I presume Thursday).

Lebanon DST change internally disputed
by Jad Baz March 26, 2023

March 26, 2023

Lebanon is going through many internal disputes surrounding the latest decision to delay DST Many institutions are refusing to comply with the change and are going to adopt regular DST on Sunday Mar 26th Those institutions include but are not limited to: - News agencies - Religious organizations - Schools, universities, etc... The refusal is mainly centered the legality of that decision and, obviously, the technical chaos it will create because of its short notice Moreover, as some of the below articles mention, this is also causing sectarian strife All of these concerns are important to bring to light in view of IANA's procedures for updating timezone data: If you would ask today "what the average person on the street would think the time actually is", it's not at all clear what the answer would be Below are some links about these latest developments: https://www.cnn.com/2023/03/25/middleeast/lebanon-daylight-savings-intl/ind… https://www.lbcgroup.tv/news/lebanon-news/693963/lbci-refuses-to-comply-wit… https://www.lbcgroup.tv/news/news-bulletin-reports/693989/lebanese-patriarc… http://www.mtv.com.lb/en/news/local/1352862/bkerke--we-are-committed-to-swi… http://www.mtv.com.lb/en/news/live_feed/1352804/mtv-will-not-comply-with-th… https://today.lorientlejour.com/article/1332635/postponement-of-daylight-sa…

March 24, 2023

The 2023b release of the tz code and data is available. It follows so closely on the 2023a release because Lebanon's government announced that Lebanon's spring-forward transition previously scheduled for the end of this week has been delayed until April 20.

Lebanon DST last minute postponed, IANA not informed!
by Jad Baz March 23, 2023

March 23, 2023

Dear timezone coordinators, My name is Jad Baz, I am a software engineer from Lebanon I just wanted to bring to your attention an issue concerning Lebanon's last minute cancellation of DST this Sunday (March 26th 2023) Lebanon, as part of the EEST timezone, is supposed to enter in DST this Sunday However, this was postponed due to Ramadan It was announced today (Thu March 23rd) by several news outlets that the Secretary General of the Council of Ministers decided to change postpone DST from this Sunday March 26th to April 21st Below, you will find a few links to news articles in English from trusted Lebanese news agencies: - https://www.lbcgroup.tv/news/lebanon-news/693669/lebanon-postpones-daylight… - https://www.mtv.com.lb/news/local/1352516/lebanon-postpones-daylight-saving… I checked the latest IANA updates from March 22nd and did not find mention of this latest development I think this decision was taken haphazardly without much regard for how this change will be propagated (as are most decisions in Lebanon, sadly...) I know my question is coming quite last minute But I'm wondering what needs to be done to save the situation as this is causing a lot of chaos (eg airlines) I looked at the procedures doc and initially thought that there must be some formal communication that needs to go out from government employees but it seems that "what the average person on street would think the time actually is" is enough So my questions are: - Are the above articles enough to make this change? Or is there any other data you need that I can help with? - Do you expect this might be amended by Sunday? If not, what's a more realistic estimate of a schedule? Thank you very much, Jad Baz

Paul, Sorry for the timing of this message; I know you are in the middle of trying to push out 2023a. At some point in the last few months the description of Asia/Bangkok in zone1970.tab changed from "Indochina (most areas)" to "north Vietnam". Is this really what you intended? -chris

[tz-announce] 2023a release of tz code and data available
by Paul Eggert via tz-announce March 22, 2023

March 22, 2023

The 2023a release of the tz code and data is available. This release contains the following changes: Briefly: Egypt now uses DST again, from April through October. This year Morocco springs forward April 23, not April 30. Palestine delays the start of DST this year. Much of Greenland still uses DST from 2024 on. America/Yellowknife now links to America/Edmonton. tzselect can now use current time to help infer timezone. The code now defaults to C99 or later. Fix use of C23 attributes. Changes to future timestamps 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. In 2023 Morocco's spring-forward transition after Ramadan will occur April 23, not April 30. (Thanks to Milamber.) Adjust predictions for future years accordingly. This affects predictions for 2023, 2031, 2038, and later years. This year Palestine will delay its spring forward from March 25 to April 29 due to Ramadan. (Thanks to Heba Hamad.) Make guesses for future Ramadans too. Much of Greenland, represented by America/Nuuk, will continue to observe DST using European Union rules. When combined with Greenland's decision not to change the clocks in fall 2023, America/Nuuk therefore changes from -03/-02 to -02/-01 effective 2023-10-29 at 01:00 UTC. (Thanks to Thomas M. Steenholdt.) This change from 2022g doesn't affect timestamps until 2024-03-30, and doesn't affect tm_isdst until 2023-03-25. Changes to past timestamps America/Yellowknife has changed from a Zone to a backward compatibility Link, as it no longer differs from America/Edmonton since 1970. (Thanks to Almaz Mingaleev.) This affects some pre-1948 timestamps. The old data are now in 'backzone'. Changes to past time zone abbreviations When observing Moscow time, Europe/Kirov and Europe/Volgograd now use the abbreviations MSK/MSD instead of numeric abbreviations, for consistency with other timezones observing Moscow time. Changes to code You can now tell tzselect local time, to simplify later choices. Select the 'time' option in its first prompt. You can now compile with -DTZNAME_MAXIMUM=N to limit time zone abbreviations to N bytes (default 255). The reference runtime library now rejects POSIX-style TZ strings that contain longer abbreviations, treating them as UTC. Previously the limit was platform dependent and abbreviations were silently truncated to 16 bytes even when the limit was greater than 16. The code by default is now designed for C99 or later. To build in a C89 environment, compile with -DPORT_TO_C89. To support C89 callers of the tzcode library, compile with -DSUPPORT_C89. The two new macros are transitional aids planned to be removed in a future version, when C99 or later will be required. The code now builds again on pre-C99 platforms, if you compile with -DPORT_TO_C89. This fixes a bug introduced in 2022f. On C23-compatible platforms tzcode no longer uses syntax like 'static [[noreturn]] void usage(void);'. Instead, it uses '[[noreturn]] static void usage(void);' as strict C23 requires. (Problem reported by Houge Langley.) The code's functions now constrain their arguments with the C 'restrict' keyword consistently with their documentation. This may allow future optimizations. zdump again builds standalone with ckdadd and without setenv, fixing a bug introduced in 2022g. (Problem reported by panic.) leapseconds.awk can now process a leap seconds file that never expires; this might be useful if leap seconds are discontinued. Changes to commentary tz-link.html has a new section "Coordinating with governments and distributors". (Thanks to Neil Fuller for some of the text.) To improve tzselect diagnostics, zone1970.tab's comments column is now limited to countries that have multiple timezones. Note that leap seconds are planned to be discontinued by 2035.
