Abstract
A device and method to control a programmable portable electronic timer to selectively provide AC power to an external electrical device by selecting a plurality of varying start times and stop times for each of at least two days, where each start time and stop time may be unique, and whereby the start/stop times define a period of timer operation to provide AC power to an external electrical device. An uninterrupted “count down” of timer information stored within the timer while AC power is unavailable to the timer is also provided, such that when AC power is restored to the timer, the providing of AC power to the external electrical device is not skewed by any period of time that the AC power is unavailable to the timer.
