Yes, but that PDF is simply page 2 of the PDF dated 2022-08-22 that we received in August 2022[1]. This was later superseded by the March 2023 cabinet decision[2]. I guess that the email we received today[3] copies the August 2022 communique merely to support the statement that Palestine's fall transition is the same that what was planned in August 2022. TZDB currently predicts that Palestine's spring transition will be April 13, 2024 at 02:00, contrary to [1] and [3] (which have the transition on March 30) but more consistent with [2] (which says Palestine used standard time during Ramadan 2023). It would be helpful if the Palestinian cabinet could confirm TZDB's guess soon, rather than wait until April next year, because if TZDB's guess is wrong it will take some time to propagate fixes out to cell phones and computers.

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
