Unfortunately, some people have moved their server time back one hour at the end of DST, but haven't adjusted the offset value in their software to cater for this. What this has meant is that in quite a few fora anyone who didn't end their DST today, now sees all their times wrong by one hour, as the server has shifted one hour relative to the user (this shouldn't happen).
Just to add to all this confusion New Zealand changed their clocks several weeks ago (um, three I think?) so I had to update everything then and have to do it again now. Doesn't help that I have one domain hosted on a server set to local time and another set to some US timezone (EST I think?) on top of all the other places I frequent. But then I've found a lot of places have NZ time an hour wrong anyway for some random reason.
