Abstract

A start date and an end date of a daylight saving time input by a user is stored in the daylight saving time information storage unit (41). The radio-controlled adjustment section (20) generates a time to adjust the time which the clocking unit (10) is clocking, by daylight saving time information and a standard time received via an antenna (AT) and a reception circuit (21), and adjusts the time of the clocking unit (10) by use of the generated time. Here, the daylight saving time determination unit (42) references to the daylight saving time period stored in the daylight saving time information storage unit (41), and adjusts the time of the clocking unit (10) so that the time becomes one which corresponds to the user-set daylight saving time.
