Abstract
The present invention is a computer system for performing processing synchronously with an internal system clock. The system includes a time information inputting part for detecting a signal for time notice sent from an external reference clock and acquiring an internal time at the present time from the system clock. The system further includes a time correction controlling part for comparing the time information together with the signal for time notice and the internal time at the time of detecting the signal for time notice and correcting the time of the system clock based on the comparison result. Further, the time correction controlling part calculates a signal interval that is a time difference in said system clock between two consecutive signals for time notice based on the internal time acquired from the time information inputting part, evaluating the calculated signal interval and judging whether or not it is required to correct the internal time.
