(If field 0x14A is set to 99, WM_BloodyDay is set to true. AIDef:Action/SetBloodyMoonEnv uses this to force a Blood Moon to be scheduled. This feature appears to be unused.)
If both Demo103_0 and Demo997_0 have not been played, time of day is reset to 78.75 (05:15).
If AIDef:Action/AdvanceTime or anything else that changes time of day was called, the actual time is updated at this moment.
