Look for a spring powered timer then. They use an AC clock motor to hold
them at, say, 5 minutes. When the power goes off the spring unwinds until
the clock goes to zero and the contacts close/open. When the power is
restored the motor rewinds the timer to 5 minutes. Looks a bit like a cheap
cooking timer on a frame.
