You  can most likely use JavaScript filesystem support to get date and time a the file was last written.  In ptotshop look at the documents metadata see if the metadata had ever been modified by a Photoshop version. if it were in may not be the version that you are currently running the data the file was written could also be the result of some other application rather than Photoshop. If the application preserved all metadata.  The latest version of Photoshop that looked at the files may be different then the version that once wrote the file.  I also do not know if Adobe updated the Photoshop version in the metadata when Photoshop open a document. The metadata in memory does not have the be the same as what is written in the files that is currently on disk.
