      Description

      If a calendar timer has a schedule less than an hour, and should fire during the DST switch it is expected to be fired like this:

      Asume : @Schedule(hour="*", minute="5/15", timezone="Europe/Berlin")
      2017 Nov. 29 1:50 CEST
      2017 Nov. 29 2:05 CEST
      2017 Nov. 29 2:20 CEST
      2017 Nov. 29 2:35 CEST
      2017 Nov. 29 2:50 CEST
      2017 Nov. 29 2:05 CET

      But the timer is fired like this:
      2017 Nov. 29 1:50 CEST
      2017 Nov. 29 2:05 CET

      All events within that hour are lost!
