There is an inconsistency between what the IBM Domino EventsSearch document shows as the time/date header information and what documents in the log.nsf show as time/date header information. Although the Header text appears to be the same, the values displayed in the EventsSearch document reflect the start/stop time of the contents within the log.
To see the EventsSearch report, in the Domino Administrator, select the Server tab, Analysis tab, and click the Log Analysis Results view. This assumes that the Log Analysis has already been run under the Tools\Analysis drop-down menu.
This issue has been reported to Quality Engineering as SPR# JIMS628SKP as an enhancement request and will be addressed in a future release of IBM Domino.
