PROBLEM TO BE SOLVED: To provide an electronic timepiece, a time correction method, and a program which can efficiently acquire accurate time data by wireless communication with an external apparatus.SOLUTION: An electronic timepiece comprises: timekeeping means; communication means for performing data transmission and reception with an external apparatus by radio at set communication time intervals; and time correction means for correcting the current time on the basis of current time data acquired from the external apparatus. The time correction means comprises: interval adjustment means for adjusting the communication time intervals according to desired accuracy while correcting the current time; update interval identification means for identifying update intervals of the current time data in the external apparatus on the basis of an arrangement pattern of the current times received by the communication means at the adjusted communication time intervals; and current time acquisition means for acquiring the current time by identifying reception timing of the current time data of which time difference between update and reception of the current time data in the external apparatus is smaller than a predetermined reference value, on the basis of the update intervals, the arrangement pattern of the current times, and communication time intervals. |
