Alarm starting 1 hour after the correct time

On Android 11, the alarm is starting 1 hour after the correct time after a trip to a place that is 1 hour time zone different.

How to solve this?

Hi. Sorry for late response. Does your device have automatic time zone setting turned on? Application listens for information about timezone change and it should reset all alarms. If not I guess the trick would be to backup all alarms and them restore them.
