I'm thinking I would like to shut down my reservation app if it is not used for a while (say 15 minutes). I'm using a file server and my philosophy is that the fewer clients that have files open the better. I would probably go to some minimal state where the app is still running but no tables are open.

I can imagine setting a timer to fire every 60 seconds and then checking to see if 15 minutes have elapsed since some time stamp was last set.

I'm trying to imagine the most general place in the app (VFE framework) to make the time stamp. Does anyone have a favorite solution to this problem?
