When viewing event logs from within Spotlight on SQL Server Enterprise (SoSSE), the log entries are off by a number of hours from the actual time when looking at the logs in Windows event viewer. The number of hours off depends on the time zone.
We have replicated this problem in-lab and raised ST12138 for this issue.
It is a Windows 2008-specific problem: rather than displaying local time from monitored server, the product shows GMT time in the Event Log drilldown.
This will be fixed in a future version of Spotlight on SQL Server Enterprise.
