Abstract
A time correction system includes a timepiece, and an electronic device that corrects the time of the timepiece. The electronic device includes a display unit, a time data acquisition unit, a control unit that causes the display unit to display an instruction time of the electronic timepiece, based on the current time, and that calculates a time correction amount from a difference between the current time and the instruction time, and a light source that transmits the time correction amount to the electronic timepiece. The electronic timepiece includes an input unit that receives an operation input for correcting the time displayed by a display unit, a solar cell that receives the time correction amount from the electronic device, and a control circuit that corrects the time displayed by an indicating hand of the display unit, based on the time correction amount.
