             Summary: EJB Timer is not fired during the ambiguous hour during the switch from summer to winter times
                 Key: WFLY-9537
                 URL: https://issues.jboss.org/browse/WFLY-9537
             Project: WildFly
          Issue Type: Bug
          Components: EJB
    Affects Versions: 11.0.0.Final
         Environment: Here CEST -> CET change from 2017 Nov. 29 2:00 CEST ....  2017 Nov. 29 2:00 CET
            Reporter: Wolf-Dieter Fink


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!
