[OT] Report to compare time files were saved

We create PDF files of our autocad drawings to link in Vantage.

I am looking for a way to compare the date modified (maybe even down
to the hour modified)of the .dwg and the .pdf of the same part.

Our part numbers for manufacture have the format xxx-xxxx-xxxxx and
purchased parts are xxx-xxxx. So the files would be like 123-4567-
89012.dwg and 123-4567-89012.pdf.

Any suggestions?

Thanks,
