I play some real-time games with friends, but we would like to set up “game hours” to avoid having to ruin sleep, etc. The game creator obviously has this ability to pause the game, but it is tedious, especially if they get knocked out.

The easiest solution (maybe it already exists?) is a web API to toggle the pause as the game administrator. Then a simple cron could take care of it. Alternately, an auto pause “game time” setting could just allow this to be set up at the game creation.
