When a time keeping apparatus is in a power saving mode, performing time display is stopped, and the apparatus periodically receives external time data and sets the data into a second time counter and an hour-and-minute time counter. When the operation mode of the time keeping apparatus is switched from the power saving mode to the display mode, the apparatus resumes display of the current time based on the counted values in the second time counter and the hour and minute time counter.
