PROBLEM TO BE SOLVED: To record a failure occurrence time using an alternative method even in a situation where time information cannot be obtained by using a realtime clock at the time of failure occurrence.SOLUTION: An information processing device includes: first recording means that, if power supply from a power source changes, obtains a time from a realtime clock and records it in a nonvolatile region; and second recording means that, if a failure occurs when the time cannot be obtained from the realtime clock, records the time recorded by the first recording means as failure occurrence time in the nonvolatile region.SELECTED DRAWING: Figure 10 |
