The problem is, even if you could tell when the file was received (you can't on the llamaserver, you'd have to use gandalf's), people could still just lie about when they started doing the turn and you'd have no way of knowing. The only way I can think of that you could actually enforce this (and this would be completely stupid and not worth doing) would be to have the turn files going to one or more third party players, who the players have to ask to give them their turns. Then, the player has to do their turn within a certain amount of time after receiving the turn file from the administrator folks they have to send the turn back to the third party player, who then uploads the turn.

Doing so would be completely insane, so I don't recommend it. I highly doubt there is any valid means of enforcing this rule... so it's best not to try to. If this game is going to happen it's going to rely on the honor system.
