发明名称 Radio controlled timepiece, electronic device and time correction method
摘要 A clocking unit (27) that clocks a time; a display unit (3) that displays a time based on clock information from the clocking unit (27); a receiving unit (20) that receives standard radio waves from transmitting stations in at least two countries or regions; a second-synchronization detecting unit (23) that detects second-synchronization information (P3) from a demodulated signal (P2) obtained by the receiving unit (20); a transmitting station determining unit (25) that analyzes the demodulated signal (P2) based on the second-synchronization information (P3) to determine a transmitting station in a country or a region; and a decoding unit (26) decodes information included in the standard radio wave from the transmitting station determined by the transmitting station determining unit (25) to obtain time information are included, and the clock information of the clocking unit (27) is corrected based on the time information obtained by the decoding unit (26).
