To test it, I made a post: http://www.thesportsrevolt.com/rebels/threads/shaq.6/
I put the time of the post in the thread, which was 11:15am Eastern Daylight Time.
The forum show's that I posted it at 11:37am EDT.
However, my client, who is also in the same time zone as me, when he looks at it, it says it was posted at 4:37 pm.
In the control panel, under Home>Options>Basic Board Information>Guest's Time Zone , I have it set to (UTC - 05:00) Eastern Time.
Is there somewhere else I need to set the time?
Also, The server that hosts this website is also in the same time zone as I am.
