INFORMATION PROCESSING APPARATUS, SYSTEM TIME SYNCHRONIZATION METHOD AND COMPUTER READABLE MEDIUM |
摘要 |
The time in the chipset of backup resources is synchronized easily at the system time. An information processing apparatus including: an operational chipset which includes a first Real Time Clock (RTC); a backup chipset which includes a second RTC: a third RTC which times system time; a difference time calculation unit which calculates a difference time between a system time periodically notified of from the first RTC of the operational chipset and the system time which the third RTC times; a holding unit which holds the difference time; a calculation unit which calculates a temporary system time which is set to the second RTC of the backup chipset to which a chipset switching operated, based on the system time of the third RTC and the difference time at the time of the chipset switching; and a configuration unit which sets the temporary system time to the second RTC of the backup chipset.
