ABSTRACT:
The invention is directed to obtaining a radio controlled timepiece that, in a case when the user who uses it moves from one country or one region to another where the time difference is different, has simplified an operation of correcting the time difference between the countries or regions and an operation of correcting the time difference due to daylight saving time's being executed. To this end, the invention provides a radio controlled timepiece1that, in addition to the radio controlled timepiece1in the prior art, it further includes offset time difference information storage means8that stores an offset time difference between a country where reference time information is formed and a country where a standard radio wave has been received and daylight saving time information storage means9that has stored therein for future use information on whether daylight saving time is being executed in the region where the standard radio wave has been received, and local standard time information forming means10that, with respect to the reference time information of the standard radio wave that has been received in a particular region, executes calculation processing by using at least either one of offset time difference information with respect to the reference time information corresponding to the particular region and daylight saving time information in the particular region, to thereby form local standard time information in the particular region.
