Best way to set up an idle timer

If the machine goes to sleep before the 300 seconds are over this 
doesn't wake it up, right?

I once tried using this "send" trick for time critical stuff, but 
that doesn't work if the machine goes to sleep. What's more, I get 
the impression that after the machine wakes up, the sleep period is 
not counted in the specified interval.
