Since the last summer time change, some applications scheduled to start at 00:15 now start start at at 01:15.
Example of the application having this problem :
Event - SCHEDMASTER.ITEM_BULK_RMSMCH_CYCL0060
Schedule - 00:15 every 2 hours weekdays
Suspend - 06:17
Resume - 00:14
and Do not trigger if active
The customer was not using the correct syntax in this context.
You should change the event statement to something like this:
Every 2 hours starting at 00:15.
Here is below the documentation to all the scheduling criteria.
You will see it has this example: Hourly starting 2 PM today.
