my time zone setting somehow changed from -5 (the correct one for me) to -4, I didn't do this myself. Akseli said in IRC that his time was an hour ahead as well. Not a big deal but seems odd. I only noticed this today.
Mine still seems to be correct, though I do use the default setting (which is UTC). DST hasn't ticked over in your region by any chance?
no, I think DST starts in March at the earliest, maybe April. And doesn't it go one hour back? I don't remember
