Abstract
A timepiece includes a clock circuit, a signal receiver configured to receive signals including time information, a processor configured to control a changing operation of changing a current time measured by the clock circuit based on the time information obtained from the signal receiver and controls a presenting operation of whether or not the changing operation is successful. The processor controls the changing operation based on a first flag indicating whether or not the signal receiver successfully receives the time information. The processor controls the presenting operation based on a second flag indicating whether or not the changing operation is successful within a predetermined period of time.
Claims13
A timepiece comprising:
- a clock circuit;
- a signal receiver configured to receive a signal that includes time information;
- and
- a processor configured to:
- perform a changing operation of attempting to receive the signal that includes the time information and changing a current time measured by the clock circuit based on the time information;
- and
- perform a presenting operation to indicate whether or not the changing operation is successful,
- wherein the processor is configured to:
- set a first flag in response to the signal receiver successfully receiving the signal that includes the time information;
- clear the first flag in response to a date of a current time counted by the clock circuit being changed;
- set a second flag in response to the signal receiver successfully receiving the signal that includes the time information, where the second flag remains set even when the date of the current time counted by the clock circuit changes;
- perform the changing operation based on the first flag being cleared;
- and
- perform the presenting operation within a predetermined period of time based on the second flag remaining set even when the date of the current time counted by the clock circuit changes.
A control method for a change of a time, comprising:
- measuring a current time;
- receiving a signal that includes time information;
- performing a changing operation of attempting to receive the signal that includes the time information and changing the current time based on the time information;
- and
- performing a presenting operation to indicate whether or not the changing operation is successful,
- wherein the control method comprises:
- setting a first flag in response to the signal receiver successfully receiving the signal that includes the time information;
- clearing the first flag in response to a date of a current time counted by the clock circuit being changed;
- setting a second flag in response to the signal receiver successfully receiving the signal that includes the time information, where the second flag remains set even when the date of the current time counted by the clock circuit changes;
- performing the changing operation based on the first flag being cleared;
- and
- performing the presenting operation within a predetermined period of time based on the second flag remaining set even when the date of the current time counted by the clock circuit changes.
A non-transitory storage medium storing thereon a program readable by a computer incorporated into a timepiece, the timepiece comprising a clock circuit and a signal receiver configured to receive a signal including time information, the program causing the computer to:
- perform a changing operation of attempting to receive the signal that includes the time information and changing a current time measured by the clock circuit based on the time information;
- and
- perform a presenting operation to indicate whether or not the change operation is successful,
- wherein the program causes the computer to:
- set a first flag in response to the signal receiver successfully receiving the signal that includes the time information;
- clear the first flag in response to a date of a current time counted by the clock circuit being changed;
- set a second flag in response to the signal receiver successfully receiving the signal that includes the time information, where the second flag remains set even when the date of the current time counted by the clock circuit changes;
- perform the changing operation based on the first flag being cleared;
- and
- perform the presenting operation within a predetermined period of time based on the second flag remaining set even when the date of the current time counted by the clock circuit changes.
