Radio controlled timepiece, electronic device and time correction method

A radio controlled timepiece comprising:

• a clocking unit configured to clock a time;
• a display unit configured to display a time based on clock information from the clocking unit;
• a receiving unit configured to receive standard radio waves from transmitting stations in at least two countries or regions;
• a second-synchronization detecting unit configured to detect second-synchronization information from a demodulated signal obtained by the receiving unit, wherein the second-synchronization detecting unit includes;
• a sampling unit configured to sequentially or synchronously detect logic “1” or logic “0” of the demodulated signal at regular intervals;
• and
• an adding unit configured to add up a number of times of detection of any one of the logic “1” and the logic “0” detected by the sampling unit,
• a transmitting station determining unit configured to analyze the demodulated signal based on the second-synchronization information to determine a transmitting station in a country or a region;
• and
• a decoding unit configured to decode information included in the standard radio wave from the transmitting station determined by the transmitting station determining unit to obtain time information, wherein
• the clock information of the clocking unit is corrected based on the time information obtained by the decoding unit, and
• the transmitting station determining unit is configured to determine the transmitting station in the country or region based on a result of addition by the adding unit in the second-synchronization detecting unit.
