Abstract:
This invention provides an electronic device (10) and an electronic clock (20). The electronic device (10) is provided with a display unit (105), a time-data acquisition unit (101), a control unit (102) that displays an indicated time for the electronic clock (20) on the display unit (105) on the basis of the current time and computes a time-correction amount from the difference between the current time and the indicated time, and a light source (103) that transmits said time-correction amount to the electronic clock (20). The electronic clock (20) is provided with an input unit (210) that accepts user input for correcting the time indicated by the display unit (208), a solar cell (201) that receives the aforementioned time-correction amount from the electronic device (10), and a control circuit (202) that, on the basis of said time-correction amount, corrects the time indicated by clock hands (2082).
