APPENDIX E Time Correction PSMS computer was. approximately 5 minutes and 49 seconds different from new plant' computer time, which is considered accurate as it is updated via satellite. The licensee conducted a time check at approximately 1000 on the morning of 9/11/87 of the PSMS computer, new plant computer and the sequence of alarms recorder (SAR) to establish their accuracy using the new plant computer as a reference. Previously, the PSMS computer was restarted and as a conse-quence its time updated. Therefore, when time check was conducted, the ' PSMS computer time was approximately 30 seconds ahead of the new plant computer, but-at the time of interest for the event, a 5 minute and 49 second time' discrep- .

ancy existed. The SAR time was 7 seconds ahead of the new plant computer time. !

There was no reason to believe tpat either the SAR or new plant computer time had been changed.
