Abstract
A receiver with timekeeping function for maintaining and displaying at least two different times of day which are each updated based on an external signal. The receiver includes first timekeeping circuitry for generating first time related information and second timekeeping circuitry for generating second time related information. Each time of day is represented by hours, minutes and seconds. The second time of day is further adjusted based on the adjustments made to the first time of day to insure that the second time of day does not gain or lose a minute of time.
