DST ended on the 2nd, so I'm a little late to this, but I just realized it when I saw that all my posts were an hour ahead, and I forgot that prophp does not auto-determine when DST is in effect, so you have to do it manually. If you do see that all of the post dates are an hour ahead, you'll want to go to the UCP, under Board Preferences, and change the option yourself.

And when DST comes back around don't forget to switch that option back on. It's not really necessary but if you do look at the posting times it could make a difference, I guess.
