One is when you open the document in Acrobat and hit Ctrl-D to view Document Properties. If the editor your users use does change ModDate or xmp:ModifyDate, then you should be able to see it in two places. However not all tools adhere to this quite a few simply leave all metadata untouched, so this method of checking isn't 100% reliable unless you know what PDF editor your users employ. Strictly speaking, modifying the PDF should change its ModDate or xmp:ModifyDate without changing its CreationDate.
