Hi KitKat,
The time that everyone sees as posts is related to the time of the server that this board is hosted. The previous server was in a different time zone than this one.
However all is not lost /images/graemlins/wink.gif
You can go and change this information, and adapt it to the current time zone that you are in. This is how to do this:
Click My Home
Click Display Preferences
In the Time Offset, put +1,+2,+3.... or -1,-2,-3... which indicates how many hours the board needs to subtract or add in order to adjust to your time zone.
Have fun
Nikos
