Abstract
A radio-controlled timepiece, including: a radio wave reception unit that receives satellite waves and extracts an incoming code sequence formatted in a prescribed format from the received satellite waves; and a processor that generates in advance an expected code sequence that is expected to be part of the incoming code sequence and detects the expected code sequence within the incoming code sequence by sequentially comparing the expected code sequence with the incoming code sequence, the processor determining a present date/time, as indicated by the satellite waves, in accordance with a timing at which the detected code sequence occurs within the incoming code sequence as measured by time kept by the timepiece, wherein the expected code sequence includes codes that change with a transmission period during which time-related information that includes satellite date/time contained in the satellite waves, which is formatted in the prescribed format, is transmitted.
