By request, I fixed the forums and articles pages tonight to display times and dates according to the timezone you've set in your user profile. I'm guessing most people haven't actually set a timezone, so it's probably still set to UTC (GMT+0:00) for you.
So, if you've ever been confused by posts from the future, be sure to update the time zone setting in your profile.
As always, let me know if you find any problems after this change.
