If the time shown on posts is off by an hour, just go into your profile and adjust it by 1 hour to make the time display correctly -- even if that means putting the incorrect time zone in your profile.
The glitch here is that the system just adds or subtracts the number of hours from local time -- it isn't smart enough to account for the fact that different countries use different dates for adjusting for Daylight Savings Time. We lost an hour last Saturday. You may need to adjust your timezone back to the correct time zone again later when your country changes for DST.
Sorry for any confusion, keeping track of all the various DST dates which are different across the world is just too much for the forum system to keep up with, I guess!
