Electronic device with clock function, time correction method and recording medium

摘要

A wristwatch (1) receives time-of-day information transmitted in the form of an infrared signal (step SA1) and then calculates the difference between the received time-of-day information and its time data. A decision is made as to whether the difference is not less than or less than a predetermined value (step SA2). If the difference is less than the predetermined value, the accuracy of the received data and the accuracy set in the wristwatch are determined by referring to the types of time-measuring references (step SA3). When the received data is higher accurate, the current time data stored by the first storage area (101) is corrected by the received time data (step SA6).
