Abstract

A communication apparatus comprises a communicator that receives a standard time from an external apparatus, a manipulation receiver that receives a time correction action from a user, and a controller that performs a timing processing for clocking time and a time correction processing for correcting the time clocked by the timing processing, on the basis of the standard time received by the communicator, or on the basis of the time correction action received by the manipulation receiver. The controller changes processing contents of the time correction processing until a prescribed time interval has elapsed, when the time clocked by the timing processing is corrected on the basis of the time correction action received by the manipulation receiver.

First claim

What is claimed is:

1. A communication apparatus comprising:
a communicator that receives a standard time from an external apparatus;
a manipulation receiver that receives a time correction action from a user; and
a controller that performs a timing processing for clocking time, and a time correction processing for correcting time clocked by the timing processing, on the basis of the standard time received by the communicator, or on the basis of the time correction action received by the manipulation receiver;
wherein the controller changes processing contents of the time correction processing until a prescribed time interval has elapsed, when the time clocked by the timing processing was corrected on the basis of the time correction action received by the manipulation receiver.

2. The communication apparatus according to claim 1 , wherein the controller suppresses, until the prescribed time interval has elapsed, correction of time clocked by the timing processing on the basis of the standard time received by the communicator by the time correction processing.

3. The communication apparatus according to claim 1 , wherein:
the communicator transmits notification information that is a signal for starting communication to the external apparatus; and
the controller:
performs notification-information transmission control that causes the notification information to be transmitted to the communicator for a prescribed interval, and
stops the notification-information transmission control until the prescribed time interval has elapsed, when the time clocked by the timing processing was corrected on the basis of the time correction action.

4. The communication apparatus according to claim 2 , wherein:
the communicator transmits notification information that is a signal for starting communication to the external apparatus; and
the controller:
performs notification-information transmission control that causes the notification information to be transmitted to the communicator for a prescribed interval, and
stops the notification-information transmission control until the prescribed time interval has elapsed, when the time clocked by the timing processing was corrected on the basis of the time correction action.

5. The communication apparatus according to claim 1 , wherein the controller does time correction in units of seconds or less until the prescribed time interval has elapsed.

6. The communication apparatus according to claim 2 , wherein the controller does time correction in units of seconds or less until the prescribed time interval has elapsed.

7. The communication apparatus according to claim 3 , wherein the controller does time correction in units of seconds or less until the prescribed time interval has elapsed.

8. The communication apparatus according to claim 4 , wherein the controller does time correction in units of seconds or less until the prescribed time interval has elapsed.

9. The communication apparatus according to claim 1 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

10. The communication apparatus according to claim 2 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

11. The communication apparatus according to claim 3 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

12. The communication apparatus according to claim 4 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

13. The communication apparatus according to claim 5 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

14. The communication apparatus according to claim 6 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

15. The communication apparatus according to claim 7 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

16. The communication apparatus according to claim 8 , further comprising a memory that stores time difference information indicating a time difference from Coordinated Universal Time, and daylight saving time information that is information related to implementation of daylight saving time;
wherein the controller does not change the time difference information and the daylight saving time information stored in the memory until the prescribed time interval has elapsed.

17. An electronic timepiece comprising:
a display that displays time clocked by the controller; and
the communication apparatus according to claim 1 .

18. An electronic timepiece comprising:
a display that displays time clocked by the controller; and
the communication apparatus according to claim 2 .

19. A communication method including:
a timing step that clocks time,
a receiving step that receives a standard time from an external apparatus;
a manipulation receiving step that receives a time correction action from a user;
a time correction step that performs a time correction processing for correcting time clocked in the timing step, on the basis of the standard time received in the receiving step, or on the basis of the time correction action received in the manipulation receiving step; and
an automati
