is still available and says confusingly:

"Daylight saving time in Palestine
Monday 18 March 2019 12:01 AM GMT Jerusalem
Daylight saving time is expected to start in the Gaza Strip and the West Bank on
Friday, March 29, bringing the clock forward.
Daylight saving time starts on Saturday, March 30, with the clock advancing 60
minutes ahead of midnight on Saturday.
In Israel, summer time will start on March 29, until October 27, 2019."
