A week is a little excessive, but what about an hour? If it's possible to get a delay up to one hour, then creating server clocks would become a _cake walk (badumtss)
I'm just curious what the limits are on delays. If 5 minutes is the farthest it can go, it's still a fairly large improvement as Lugnut has pointed out (thank you by the way, I missed a 0 so it seemed like it was still just a 30 second delay.)
