how to create an interval of hours?

Hey folks

I'm in need of some help with one particular element of a new interactive Website which I am currently developing. There will be a series of games, but, here's where I am currently stumped.

The theory is I only want the user to be able to play the game once every 3 or 6 hours. I had thought of using time() but then I realised that it Would be easy to cheat by adjusting the time on your pc.

So I figure I need to use gmtime() somehow, but I'm not having any luck, the php manual doesn't make much sense either.

Any ideas appreciated
Thanx

Jack

You can still use time() because time() returns the time on the server, not the client - and the user can't change the time of the server.
