I have no idea why X-Fire seems to start events at odd times. Either it's broken or I'm not inputting the times correctly. I'm blaming X-Fire anyway.

All events start at 8pm UK time. Ignore any bizarre notifications at early hours in the morning and so on.

Lameness...

I have reset the oddly scheduled events. This seemingly makes no difference, as X-Fire now has them scheduled from 4am - 8am.
