Thanks for the info. I installed the attached proposed patch into the TZDB development repository. This patch affects only commentary, as the repository's data for spring 2023 already match what you sent. We plan to release a new TZDB version soon. As I mentioned earlier, in TZDB we are guessing that next year Palestine will spring forward on 2024-04-13 at 02:00, and that the year after that it will spring forward on 2025-04-05 at 02:00. If these guesses are incorrect, please let us know as soon as possible. The longer the Palestinian government waits to decide about clock changes in 2024 and 2025, the more likely its residents' clocks will be wrong, due to the delay in propagating TZDB data to cell phones and computers. Thanks again.
