Abstract
An electronic device includes at least an acquisition unit, an input unit, a time correction amount calculation unit, and a transmitting unit. A timepiece includes at least a receiving unit, a power storage unit, a drive unit, and a control unit. The input unit receives an input of the time displayed by the display unit of the timepiece. The time correction amount calculation unit calculates a time correction amount for correcting the time of the timepiece from a difference between the time, the input of which is received by the input unit and the current time acquired by the acquisition unit. The transmitting unit transmits the time correction amount to the timepiece by using light. The receiving unit receives the time correction amount. The power storage unit stores electricity by using power converted from the light. The drive unit drives the indicating hand. The control unit corrects the time displayed by the indicating hand, based on the time correction amount received by the receiving unit. The control unit controls a power storage period in the power storage unit and a receiving period in the receiving unit so as to receive the time correction amount in the receiving period.
