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 timepiece 1 that, in addition to the radio controlled timepiece 1 in the prior art, it further includes offset time difference
information storage means 8 that 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 means 9 that 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 means 10 that, 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.
