Posted on October 31, 2014 by Garth

This week one of our developers highlighted the fact that the DBMS_SCHEDULER on one of our 11.2.0.3 databases was running jobs an hour later than scheduled until just recently, when the clocks went back (26/10/2014) for British Summer Time (BST) …and now they’re running on-time again! I’d not seen this before, and at first I thought we
