Lebanon DST change update - central bank to use two timezones
by Jad Baz March 25, 2023

March 25, 2023

Lebanon's central bank said it would only adopt government decision (of postponing DST) for work shifts and schedules but would stick to regular DST time in its systems and transactions https://www.mtv.com.lb/news/%D9%85%D9%80%D9%80%D8%AD%D9%80%D9%80%D9%84%D9%8… https://twitter.com/BeirutCityGuide/status/1639653667694428161?s=20

[tz-announce] 2023b release of tz code and data available
by Paul Eggert via tz-announce March 24, 2023

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. This release contains the following change: Briefly: Lebanon delays the start of DST this year. Changes to future timestamps This year Lebanon springs forward April 20/21 not March 25/26.

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

DST Change in Lebanon
by Rany Hany March 23, 2023

March 23, 2023

Hello, Lebanon has extended daylight savings time until April 20 2023 (exceptionally this year). It's so that people fasting this ramadan stop their fasting at 5PM instead of 6PM.

Asia/Bangkok

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.

I've never built with that particular combination, and you exposed a couple of typos. I reproduced the problem artificially on GNU/Linux by building with "make CFLAGS='-DHAVE_SETENV=0'" and installed the attached patches. This fix should appear in the next release, which should be soon.

Dear Paul, I'm Afaf EL MAAYATI from National Telecommunications Regulatory Agency in Morocco. Actually, in the current version of Time Zone Database (https://www.iana.org/time-zones) for Africa region, and especially for Morocco, it’s mentionned that a program will be running to implement the transition dates. According to this program, the next transition dates (during 2023) are as below : - March 19, 2023 (switching to GMT). - April 30, 2023 (switching back to GMT+1). In fact, we will switch back to GMT+1, advancing 60 minutes, on Sunday, April 23 at 2:00 a.m (not on April 30). Please refer to the official annoncement, published by the Ministry of Digital Transition and Administration Reform: https://www.mmsp.gov.ma/fr/actualites/passage-%C3%A0-l%E2%80%99heure-gmt-%C… So, would you please update the program, in order to consider « April 23 at 2:00 a.m » (for switching back to GMT+1). Thank you in advance for your feedback and for your habitual support. Thank you.

Maryland bill status
by Arthur David Olson March 21, 2023

March 21, 2023

Crossover day has come and gone in the Maryland state legislature; bills not passed by one of the two chambers by crossover face substantial hurdles in gaining approval. Neither the House-side nor the Senate-side bills shifting Maryland to permanent DST (with the potential for a short-notice shift) made it out of committee. Links to bill status below. My guess: the bill (it's actually the same bill, cross-filed) will be back next year.-( @dashdashado https://mgaleg.maryland.gov/mgawebsite/Legislation/Details/hb0165?ys=2023rs https://mgaleg.maryland.gov/mgawebsite/Legislation/Details/sb0268?ys=2023rs

How Time Zones Are Coordinated
by Kim Davies March 15, 2023

March 15, 2023

Yesterday we posted a short article that gives a primer on this project: https://www.icann.org/en/blogs/details/how-time-zones-are-coordinated-13-03… It is also being circulated to attendees to our major conference being held in Mexico this week. An objective in posting this is to better raise awareness with policy makers to plan time zone rule changes well in advance so that changes can be thoroughly disseminated. There are many government representatives from around the world at this Mexico meeting so hopefully this can contribute to spreading the word. kim

Which should be the same as Matamoros, Tamaulipas, México. (America/Matamoros) instead of (America/Monterrey).
