APC Daylight Savings Time Issues?

The Internet Storm Center says it has received reports today of Daylight Savings Time problems with some versions of APC power management software. Here’s what the ISC is reporting:

“I have a box running APC Powerchute on Windows Server 2003 SP1 that was scheduled to shutdown and restart one of my systems at 3:00 AM today but didn’t do the shutdown until 4:00 AM. According to my staff, APC had reported that earlier editions of Powerchute had a DST issue, but 7.0.5 was corrected, yet this doesn’t appear to be correct. The W2K3 server did update the time correctly to the new DST at 2:00 AM this morning and is reflecting the correct Eastern DST. … Since then, I have checked other W2K3 boxes with this Powerchute version and found that the change actually advanced my scheduled shutdown time by one hour rather than actually correcting DST. So it looks like a problem exists with Powerchute.” … So those of you that are running Powerchute software may want to check your systems.

As with most DST problems, this isn’t an operational showstopper, but if you’re trouble-shooting these issues today, it’s one to add to the checklist.
