My Sony Xperia XZ2 compact trolled me today on April 1st by not going off at my regular weekdays 7:30 schedule. Note that we switched from winter time to summertime during the weekend. I assume the alarm schedule works with a fixed UTC offset which is set when the alarm is created (months ago) and I expect it to behave normally tomorrow morning since I've turned it off and on again (taking the new UTC offset into account). Is my assumption correct and is this Sony only?
