Due to the return from Daylight Saving Time October has one additional hour. Adding a duration of 30 times the number of milliseconds per day brings you to Oct 30, 23:00.

Not really sure where the problem was, replacing the ad-hoc date code with joda time methods solved it. _______________________________________________ rules-dev mailing list rules-dev(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-dev
