All user register/posts dates are the same

Hello, When a user registers or makes a post, it loggs the date and time correctly in the database. The forum will show the correct date information for "today" and "yesterday" in the userlist when looking at the registered date, but anytime after "yesterday", all the dates show May 5, 2007 for EVERYTHING. The forum was not even installed yet on May 5. In the actual forum, you can post something, and as soon as the post is completed it shows the correct time with May 5 next to it for the date.

I tried playing around with the server time zone settings, but it didnt do anything. Also, I dont think its that because the time and date is correct for two days before it defaults to May 5.

Any ideas??????

P.S.- Just checked my database, and it looks like its storing the registered time and date fine, because all the values are different. May 5 is showing on all the posts and the user list registered date.
