Perhaps something simple like "This function returns t if the file filename1 is newer than file filename2, as reported by your operating system."

IMO that doesn't help. It just suggests that a reader look to the operating system doc for how it defines/reports a "newer" file. Look for the words "newer" and "file" in the OS doc?

The point of the bug report is that this comparison (whatever the OS, presumably) has something/mostly to do with the latest modification date of the file - something equivalent, or similar, to what Unix/Linux`touch' ends up with as the resulting time/date.

That's mostly to do with file content: at a _first approximation_ it's the date of the last content change - on any OS presumably.
