Satellite radio wave receiving device, radio controlled timepiece, method of outputting date and time information, and recording medium

A method a radio controlled timepiece comprising:

• a time counting circuit;
• a satellite radio wave receiving device comprising:
• a receiver;
• and
• a first processor;
• and
• a second processor,
• wherein the method comprises:
• controlling the time counting circuit to count date and time;
• controlling the receiver of the satellite radio wave receiving device to receive a satellite radio waves;
• acquiring, by the first processor, primary date and time information, for correcting the date and time counted by the time counting circuit, from the satellite radio waves received;
• in response to completion of acquisition of the primary date and time information from the satellite radio waves received:
• setting, by the first processor, an output timing for outputting a timing notifying signal, the output timing being set to be a predetermined delay from a time of the completion of acquisition of the primary date and time information, irrespective of synchronization with seconds indicated by the primary date and time information;
• outputting, by the first processor, the timing notifying signal at the output timing;
• determining, by the first processor, date and time of outputting the timing notifying signal based on the primary date and time information;
• outputting, by the first processor, a set date and time signal indicating the date and time of outputting the timing notifying signal;
• detecting, by the second processor, the timing notifying signal output from the first processor;
• counting, by the second processor, elapsed time from detection of the timing notifying signal;
• detecting, by the second processor, the set date and time signal and acquire, by the second processor, the date and time of outputting the timing notifying signal indicated by the set date and time signal detected;
• and
• correcting, by the second processor, the date and time counted by the time counting circuit based on the elapsed time counted and the date and time of outputting the timing notifying signal.

A non-transitory computer-readable recording medium recording instructions for causing a first processor of a satellite radio wave receiving device and a second processor to at least perform:

• controlling, by the second processor, a time counting circuit to count date and time;
• controlling, by the first processor, a receiver of the satellite radio wave receiving device, to receive satellite radio waves;
• acquiring, by the first processor, primary date and time information, for correcting the date and time counted by the time counting circuit, from the satellite radio wave received;
• in response to completion of acquisition of the primary date and time information from the satellite radio waves received:
• setting, by the first processor, an output timing for outputting a timing notifying signal, the output timing being set to be a predetermined delay from a time of the completion of acquisition of the primary date and time information, irrespective of synchronization with seconds indicated by the primary date and time information;
• outputting, by the first processor, the timing notifying signal at the output timing;
• determine date and time of outputting the timing notifying signal based on the primary date and time information;
• and
• outputting, by the first processor, a set date and time signal indicating the date and time of outputting the timing notifying signal;
• detecting, by the second processor, the timing notifying signal output from the first processor;
• counting, by the second processor, elapsed time from detection of the timing notifying signal;
• detecting, by the second processor, the set date and time signal and acquiring, by the second processor, the date and time of outputting the timing notifying signal indicated by the set date and time signal detected;
• and
• correcting, by the second processor, the date and time counted by the time counting circuit based on the elapsed time counted and the date and time of outputting the timing notifying signal.
