I need to be able to hold the game if something comes up, and I can't necessarily do that if the gen time ends up being while I am asleep (this is more of an issue for me than for most hosts, as I sleep more than usual).

Also, I posted that it would be a fixed schedule in the OP, and everyone signed up presumably having read it. It would be irresponsible of me to change the agreed rules of a game while it is in progress.

We will retain a fixed schedule.
