Incorrect Post Date being applied during import
 

I am running Impex to convert a forum from DCForum+ to vBulletin.

However, some posts have incorrect posting dates assigned to them.

For example:

http://woodworkersjournal.com/forum/...post-revisited

In this situation, the replies to the original post show correct posting dates from 2003, but the original posting shows a post date of today at 2 am. This forum should not have any entries since last Friday, 5/14/2010

The forum in its current state:

http://woodworkersjournal.com/forum/

The forum I am converting from:

http://wwjtemp1.mn2.visi.com/dc/dcboard.php

(I've submitted this via Support as well, but I'm hoping to get some kind of resolution sooner rather than later)
