Body
RollupMapper with a DayWindow always expects 24 hourly keys, so a local-timezone upstream mapper breaks on DST days: spring-forward (23h) leaves one expected key that never arrives and the run is held forever; fall-back (25h) drops the extra hour's events.
Current workaround (in the partition docs / known limitations): use UTC partition keys.
This tracks making the calendar windows DST-aware so the expected key set matches the real number of hours, instead of relying on a UTC workaround.
