Right now in Syria government made a decision to cancel day light saving (DST) in Syria but for some reason smartphones (android and ios) devices reserve a change to it clock so the clock in the all smartphones are now late for an hour so I hope to fix this mistake and reasove the issue 

We first received notice of this change for Syria on 5 October 2022 and published it in version 2022e of our data on 11 October 2022.

This was about two weeks before the change took effect about 18 hours ago, which is not a lot of time.

Data updates take some time to propagate via telecommunications and vendor support down to people's cell phones and computers.  So it is unfortunately not surprising, given the short notice, that many devices haven't been updated before today's change went into effect and are now off by an hour.  Once we've published updated data, it is up to these downstream providers to apply it in a timely fashion.  For more on this topic, please see:
