My suggestion (until they fix the problem) is to remove that check for Daylight Time on settings. However, they could adjust the clocks at any time, so it would be best for Auctiva to recommend or state when they will fix to avoid scheduled submission errors.
This clock problem seems like Deja Vu. Was that Bill that just passed by with a Groundhog driving?

And, WE GOT 20 INCHES OF SNOW IN 24 HOURS in COLUMBUS IN MARCH!

Update: Well, it's off. Does the expression: "It's later than you think." make your head spin.
