A summer time start date and end date inputted by a user are stored in a summer time information storage unit (41). A radio control unit (20) generates a time for correcting the time clocked by a clocking unit (10) based on the summer time information and the standard time received via an antenna (AT) and a reception circuit (21) and corrects the time of the clocking unit (10) by that time. Here, a summer time judgment unit (42) references the summer time period stored in the summer time information storage unit (41) and corrects the time at the clocking unit (10) so that the time corresponds to the summer time set by the user. |
