The patches I applied to my various systems seem to have all worked for now.  The only Daylight Savings Time bug I've seen has been with NetBackup 6.0MP4.  For some reason, I had some backups run about 7 times last night, over and over and over again.  Fortunately they were differential backups, so they were very small and fast, and didn't use a lot of tape.  Apparently I'm not alone, and since we all experienced this for the first time on the same day, we're guessings it's related to the time change.
