Now that Daylight Savings Time is now official in most of the world, and since phpBB doesn't automatically adjust for DST, you may want to
edit your preferences to update your timezone. I'm in Eastern time, and thanks to DST, I shifted from GMT-5 to GMT-4; similarly, most people will simply add one hour. (And, of course, now come the long evenings, which I think almost any geek loves. 8))
