Abstract
The power outage timer (36, 136, or 236) forms a part of an electronic watt-hour meter (10) having a microprocessor (22), a real time value memory and a real time clock signal input from a voltage supply (23). The power outage timer (36, 136, or 236) is coupled to the microprocessor (22) for generating a signal when, after a power outage, power is restored, such signal being indicative of the time duration of the power outage and being input to the microprocessor (22) so that the microprocessor (22) can update the real time value in an EAROM (32) to reflect the correct real time.
