The radiowaves including time data are received at receiving means (2, 3, 1). When the current time data in current time counting means (7) has been corrected by correction means (1) on the basis of the current time data obtained at the receiving means, it is judged whether or not an alarm time is present between the time data before correction and the time data after correction. If an alarm time is present, the user is informed of the alarm time. This avoids the problem of failing to inform the user of the alarm time at that day. Furthermore, the correspondence between the current time data in the current time counting means (7) and the time data in different functional means (20) is prevented from changing as follows when the current time data has been corrected on the basis of the received time data, the time data in the different functional means (20) is also corrected as much as the same correction time, or while the different functional means (20) is operating, the time correcting operation is prevented from being carried out even if the time correction timing has been reached. <IMAGE> |
