It looks like this is an artifact of the time change from Daylight Savings to Standard time. The schedule should correct itself for the next events after Nov 17th.
That is a pretty lame excuse since after Nov 17th still means this war starts early rather than late. How difficult is it to change the schedule?
The next event after Nov 17th's Armada War will start in the afternoon so the schedule will be back to an alternating morning/afternoon rotation.
