Abstract

Peripherals and send timing information presenting a timing of acquiring time information to a central. The central changes the timing in the received timing information so that the timing presented by the timing information received from the peripheral does not overlap with the timing presented by the already received timing information of the other peripheral. The central makes the peripheral change a setting of the timing information based on the changed timing information.

First claim

What is claimed is:

1 . A wireless communication device comprising a processor, wherein
the processor measures time; acquires time information from another wireless communication device and corrects the measured time; sends timing information presenting a timing of acquiring the time information to the other wireless communication device; and receives notice of change of the timing information from the other wireless communication device and changes a setting of the timing information based on the notice of change.

2 . An electronic timepiece comprising the wireless communication device according to claim 1 .

3 . A wireless communication method, comprising:
a timing information reception step of receiving from a wireless communication device timing information presenting a timing of the wireless communication device acquiring time information; a determination step of determining whether the timing presented by the timing information received in the timing information reception step overlaps with a timing presented by timing information of another wireless communication device other than the wireless communication device; a timing information change step of changing the timing presented by the timing information when the overlapping is determined in the determination step; and a change notification step of sending to the wireless communication device notice of change to change a setting of the timing information of the wireless communication device based on the changed timing information.

4 . The wireless communication method according to claim 3 , further comprising:
a clock rate information reception step of receiving from the wireless communication device clock rate information presenting deviation of the time measured by the wireless communication device, wherein in the timing information change step, the timing is changed based on the clock rate information.

5 . The wireless communication method according to claim 3 , wherein
in the timing information change step, the timing is changed by shifting the timing by a specific interval either to an earlier timing or to a later timing than the timing presented by the timing information of the other wireless communication device.

6 . The wireless communication method according to claim 4 , wherein
in the timing information change step, the timing is changed by shifting the timing by a specific interval either to an earlier timing or to a later timing than the timing presented by the timing information of the other wireless communication device.

7 . A non-transitory computer-readable recording medium on which programs are recorded, wherein the programs allow a computer to function as:
timing information receiver which receives from a wireless communication device timing information presenting a timing of the wireless communication device acquiring time information; determiner which determines whether the timing presented by the timing information received by the timing information receiver overlaps with a timing presented by timing information of another wireless communication device other than the wireless communication device; timing information changer which changes the timing presented by the timing information when the overlapping is determined by the determiner; and change notifier which sends to the wireless communication device notice of change to change a setting of the timing information of the wireless communication device based on the changed timing information.
