Lebanon DST change reverted
by Rany Hany March 27, 2023

March 27, 2023

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). Sources: * https://www.lbcgroup.tv/news/breaking-news/694239/%D9%85%D8%B9%D9%84%D9%88%… * https://www.mtv.com.lb/News/%D9%85%D8%A8%D8%A7%D8%B4%D8%B1/1353208/%D9%85%D…

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…

Time Zone Iran
by Patrick.Stergonschegg＠orf.at March 26, 2023

March 26, 2023

Hello, I just noticed that the Windows time zone for "UTC +03:30 Tehran" is probably being computed incorrectly. It seems that DST +1 is being added, although Iranian Government announced that they will not switch to DST anymore, beginning in 2023. Official IR News Agency announcement: http://irna.ir/xjJ3TT Current Time: https://time.ir I assume that Microsoft imports IANA time zone data: http://bit.ly/3ZmGzTE In the file tzdata2023b\asia on line 1625 it says: 3:30 Iran +0330/+0430 I assume the line should be changed and a new line should be added, e.g.: 3:30 Iran +0330/+0430 2022 3:30 - +0330 More ressources: http://bit.ly/3lQC9qp https://www.timeanddate.com/worldclock/iran I am looking forward to any feedback. Thanks a lot, Patrick

Lebanon DST change update - central bank to use two timezones

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. (Thanks to Saadallah Itani.) Here are links to the release files: https://www.iana.org/time-zones/repository/releases/tzcode2023b.tar.gz https://www.iana.org/time-zones/repository/releases/tzdata2023b.tar.gz https://www.iana.org/time-zones/repository/releases/tzdb-2023b.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 71faa2a55db2c9f21f4099b58c28536673982e0a dated 2023-03-23 19:50:38 -0700 and tagged '2023b' in the development GitHub repository at <https://github.com/eggert/tz>.
