With Daylight Saving Time coming up this weekend in the United States,there is a defect that was fixed prior to the Zenoss 3.0 release that still affects Zenoss 2.5 installations. Without this patch, maintenance windows may not be properly scheduled, resulting in events being processed that should not have been reported.

and then restart their Zenoss server.
Users of Zenoss 3.0 and later are unaffected by this defect.
