July 8, 2026

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.

Re: [tz] Time for a Lunar time zone? -Brooks
by Paul Eggert July 11, 2024

On 3/2/23 09:51, Brooks Harris wrote: > Will we need DST on the Moon? :-) I hope not! The Moon's axis tilts only 1.5°, much less than the 23.5° of Earth's axis, so seasonal effects on sunlight duration are much less intense on the Moon and there should be less need for Earth-like DST. A more pressing issue is that the length of day (including daytime and nighttime) varies more on the Moon. Local Earth days vary by at most 0.008 hours from the mean of 24 hours (this variation is due to the eccentricity of the Earth orbit and the obliquity of the ecliptic). So people who think that every local Earth day is exactly 24 hours are not far off. Local lunar days, in contrast, are roughly 29.5 ± 0.25 Earth days (again, this includes both lunar daytime and lunar nighttime). That's more slop to deal with, relatively speaking, and dealing with varying-length days could be a bit of a problem for civil time on the Moon. Presumably ESA's boffins are on top of this.....

Danish standard time will probably officially be based on UTC
by Jonas Nyrup Sept. 9, 2023

Sept. 9, 2023

Since 1893-03-29 Danish standard time has been defined as "the mean solar time for the 15th degree of longitude east of Greenwich" (machine translated of the offical law). With the introduction of UTC we didn't update that law, but we did start using UTC+1 as standard time in practice. So for around 50 years maybe only astronomers have been following the law. The Minister of Transportation has now proposed a bill to update the law to define Danish standard time as UTC+1 to keep up with reality. At the first reading all political parties expressed their support and jokingly noted that "it was about time". The updated law is expected to take effect on 2023-03-26. The current law: https://www.retsinformation.dk/eli/lta/1893/83 The bill: https://www.ft.dk/samling/20222/lovforslag/l19/index.htm Tom Scott on the subject: https://www.youtube.com/watch?v=yRz-Dl60Lfc Jonas Nyrup

Buggy %z behaviour in strftime
by Almaz Mingaleev May 16, 2023

May 16, 2023

Attached code prints "+0000 America/Los_Angeles" both with glibc and with linked ToT strftime implementation. On MacOs it prints "-0800 America/Los_Angeles". Is it a known issue?

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>.
