*Asia/Gaza POSIX TZ string (generated by zic)*: EET-2EEST,M3.4.4/50,M10.4.4/50"
The rule specifies that DST in 2024 starts on April 20th. Why then does the POSIX TZ string use M3.4.4? Is this a bug? or is there any other reason? Thanks.
Hi Meng Chen, Have you checked the tzset(3) docs for TZ? IIRC these say after the specific rules up to 2086, use alternative standard+1 from March 4th Thursday at 50h UTC offset, reset to standard UTC+2 from October 4th Thursday at 50h UTC offset => Saturday after 4th Thursday at 02:00. -- Take care.
