AutoCAD 2013 :: Wrong Date On DWG To PDF Files

I've recently begun using the "DWG to PDF.pc3" plotter/printer for making PDF files of my AutoCAD 2013 drawings because it's quite a lot faster than using the "Adobe PDF" plotter/printer that I have been using up to now.

But today I noticed something very odd: After I create a PDF file using the "DWG to PDF.pc3" plotter/printer, when I go into Windows Explorer (the file manager) and click on a file to select it, the file shows the "Date Created" and "Date Modified" as being "11/27/2007 9:11 AM" even though the file was actually created today, 4/18/2013 at 3:01 PM. If I right-click the file and select Properties, the General tab shows this incorrect date and time for the Created and Modified data, as well as the Accessed data, which you can see in screen capture 1 attached.

Before you ask the obvious: yes, my computer's date and time ARE set correctly. This is as if AutoCAD has some sort of "internal" clock that's set to the wrong time, the wrong dthe wrong year, and is assigning that wrong information to the finished PDF file... very weird. 

And then opening the file in Acrobat itself, when I click on the File menu and then on Properties, the Document Properties window appears and shows the data contained within the file: and it is the CORRECT Created and Modified date & time! You can see this in screen capture 2, also attached.

So it seems as if the "DWG to PDF.pc3" printer/plotter is creating the file correctly, and placing the correct Date and Time data inside the file for Acrobat's use, but is coming up with this bizarre time on a date over 5 years in the past as the data that Windows "sees" in the file's Properties.

I'm simply baffled by this. It wouldn't bother me so much except for the fact that we make many corrections and updates to files without changing or "dating" the file name, and my boss frequently asks me to sort the files within a folder by the Date Modified, so we can find the latest revision.
