Abstract:
     To make a time instant correction possible while suppressing an electric power consumption due to a reception of radio wave containing a time instant information. When a reception means has been made into its operation state in order to receive the radio wave containing plural markers disposed in predetermined positions and the time instant information, in a case where.the marker initially received has been a reference marker M corresponding to an exact minute position, the time instant information is obtained by continuing the reception intact, and a time instant of a clock means is corrected and displayed to a display means. When the marker initially detected has been a position marker P, the reception means is made into its non-operation state. After 9 seconds from this point in time, the reception means is made again into the operation state in order to receive the reference marker M appearing after a constant time. This operation is repeated till the reference marker M can be detected, thereby performing the time instant correction.
