Calibre will show if a book in its library is present on a connected reader, however is there any way to display if the two are the same "version", i.e. same file date/time (perhaps within a tolerance).

I have a number of readers and sometimes will update a book and upload it to my main reader (perhaps when I notice an error while reading), but will forget to update one of the other readers. The ability to check if the Calibre library and a connected reader have the same version would be useful to know just which ones need re-uploading.
