Abstract
A radio-controlled timepiece includes the following. A timekeeping unit keeps date and time. A satellite radio wave receiving unit receives a transmitting radio wave of a positioning satellite. A receiving term setting unit sets a receiving term with the satellite radio wave receiving unit. A date/time obtaining unit obtains date/time information from the transmitting radio wave received by the satellite radio wave receiving unit. An elapsed time counting unit counts elapsed time from when the date and time is obtained by the date/time obtaining unit. A first judging unit judges whether the elapsed time is less than a first reference time determined based on a timekeeping error of the timekeeping unit and a format of a signal transmitted from the positioning satellite.
