Under my home then go into edit display preferences
There is something that says server time, type in the number of hours different. So if it reads 12:36 and it is really 3:36, put the number 3 in the space and it will change.
If you make a post at 5pm (your time) but on the thread it shows up as 3pm.... then you put a '2' in the server time and it will advance the time of all the threads 2 hours... which should correesond with your time zone.
