Delaying ACU spawns

Any way to make a player spawn later into the game, same 20-60 seconds after the start of the game?



I was hoping to make a map where, among other things, 2 civilian factions would have a little battle before the players spawned.|||this was brought up recently, and Duncane inputted that he's quite certain it's possible; i'd go read through his last 50 or so posts and see what he said.
