Abstract:
1. An electronic musical apparatus of a type which boots up when a power is supplied and shuts down when the power is removed, said apparatus comprising: an internal clock which is not backed up by an uninterruptible power supply and stops counting time when a power supply to the apparatus is shut down; a time information acquiring device which externally acquires time-of-day clock counting information upon boot of the apparatus or prior to execution of processing which needs a reference time-of-day clock counting; a judging device that judges whether the time information acquiring device successfully acquires the time-of-day clock counting information; a clock correcting device which corrects said internal clock to run with a time-of-day counting based on the externally acquired time-of-day clock counting information if the judging device judges that the time-of-day information has been successfully acquired and based on a predetermined default time-of-day or user-set time-of-day set by a user if the judging device judges that the external time-of-day clock counting information acquisition has been unsuccessful; and a process executing device which executes the processing which needs a reference time-of-day clock counting according to the time-of-day counting of said internal clock as corrected by said clock correcting device.
