Yet another

I think that the switch and time of day is done using a timer.

In answer to your second question, have a read through this thread: http://zelaron.com/forum/showthread....ght=timer+beer

I've got a post some way down in which I've attached screenshots of the screens with events after a timer. You should be able to take that information and modify it for your own needs. I've got the demo somewhere still, I think. I'll upload that once I've sorted out my computer.
