I found this 20a switch/timer at Lowe's. I would have to (1) install/rewire in the wall near the receptacle, or (2) put together a 2 gang box with the timer, receptacle, and a short SO cord/plug. The other units they offer have a dusk/dawn sensor and some "time after" settings, which I don't think will work in an office setting. I'll check HD later on.
