A radio-controlled timepiece has a reception means that receives a standard radio signal containing time information; a demodulation means that demodulates the standard radio signal received by the reception means and outputs a demodulated signal; a waveform discrimination means that discriminates the waveform of the demodulated signal based on a specific waveform discrimination standard, and outputs a code corresponding to the waveform; a time information conversion means that converts the code output by the waveform discrimination means to time information; and a waveform discrimination standard changing means for changing the waveform discrimination standard. |
