The android app reports alarms 5 minutes earlier?

Have I missed a change or am I st…?
I am always getting a time 5 minutes BEFORE the set alarmtime sent to openHAB. In the rule I am converting from from DSL to ECMA I used to subtract exactly those 5 minutes (tested in OH2, at least I think I did it???).
Was there a change in the app?

There hasn’t been a change in the openHAB app. Maybe your alarm clock app received an update and now schedules the alarm differently. I could be set 5 minutes earlier to make sure the device is awake when the alarm should ring.

Thanks for the fast reply.
Will report what the (stupid) cause it was/is if I find it.
