Electronic timepiece

An electronic timepiece comprising:

• a receiver that receives a standard time signal, which carries a first level signal and a second level signal in 1 second, and transmits a signal containing first data bit and second data bit in the 1 second by a combination of the first level signal and second level signal;
• a detector that samples the signals received by the receiver and detects the signal level;
• a calculator that, based on the signal levels detected by the detector, calculates the total signal width of the first level signal, and the continuous second level signal time, in 1 second;
• and
• a code evaluator that evaluates the code of the signal, and detects a signal position indicating which second the signal represents in a frame including signals for a 60-second period;
• the signal containing a first code, second code, and third code;
• the total signal width of the first level signal in 1 second is the same in the first code and the second code;
• the first code being a code that transmits the first level signal in 1 second;
• the second code being a code that transmits two first level signals separated by a second level signal in 1 second, the values of the first data bit and the second data bit each being different from the values in the first code;
• the third code transmits, in 1 second, one first level signal of the same signal width as the first first-level signal of the two first level signals in the second code, the value of the first data bit being the same as the second code, and the value of the second data bit being different from the second code;
• at a signal position where the information to acquire is contained in the first data bit, the detector stops sampling signals in the 1 second when the continuous time is greater than or equal to a previously set reference time, and the code evaluator determines the value of the first data bit based on the total calculated by the calculator;
• and
• at a signal position where the first data bit is a fixed value, and the information to acquire is contained in the second data bit, the detector continues sampling until the previously set stop-sampling time, and the code evaluator determines the value of the second data bit based on the total calculated by the calculator and the signal position.

• the standard time signal including a first period in which the signal level changes according to the value of the first data bit, and a second period in which the signal level changes according to the value of the second data bit;
• the signal includes a first code and a second code;
• the first code transmits the first level signal in the first period, and transmits the second level signal in the second period;
• the second code transmits the second level signal in the first period, and transmits the first level signal in the second period;
• and
• the code evaluator selects either the first period or the second period according to the signal position, and evaluates the code of the signal based on the signal level detected in the selected period.
