Timers will start as soon as the server hits midnight GMT. Events should enter their warmup periods around 20mins after the previous one ends.
The intention with online players being eligible for rewards between the preset time periods is that we can have some testing with some more concentrated numbers at that time. (Though events will run the whole day (actually the whole weekend)).
I should be on myself at some point between those hours but I'm not really going to have the opportunity to do much in the way of GM assisting (I'm getting married in 1 month so spare time isn't something I have a lot of at the moment ).
plus we want to check the automated system is working correctly in a live environment.
