I just noticed that dates in forum posts today are showing up as January 12, 2008. It seems there's something that is converting the shorthand 12/01/2008 into the twelfth day of the first month or something like that. In noticing this, I also noticed that posts from last month are all dated "11, 2008". It seems as if there is a function that is trying to convert the day part of the date into a long-hand month and returning blank if the day is 13+.

I should clarify that the mis-displayed dates are only in the forum topic lists, not the posts themselves, the correct dates are shown there.
