Until yesterday (no DST) the astro2 binding worked flawlessly, since today (change to Daylight Savings Time) the trigger events and DateTimes are off by one hour:
Snapshot #844, binding version 18.104.22.168703171402
Example: civilDawn, earliest set to 08:30, no offset: DateTime shows 09:30, event is triggered also at 09:30:
DateTime item shows 09:30 instead of 08:30, local time on Raspberry is up to date.

I also tried DateTime for Sunset, same problem, off by one hour.
Maybe not a binding problem if related to
