wrong info in Document Properties

I've seen it before but haven't paid much attention to it. I go to pull up an old file and I see this

Those two dates should, at the least, be reversed. The file was actually created 9/23/2013. I know this because we use a footer tag in all our documents that includes this info, as well as, what designer created it and the location of the png proof file for emailing. So how was it "created" in the future?
