-The function returns zero if the buffer has no recorded last
-modification time, which can happen, for instance, if the record has
-been explicitly cleared by @code{clear-visited-file-modtime} or if the
-buffer is not visiting a file. Note, however, that
-@code{visited-file-modtime} can return a non-zero value for some
-buffers that are not visiting files, but are nevertheless closely
-associated with a file. This happens, for instance, with dired
-buffers listing a directory. For such buffers,
-@code{visited-file-modtime} returns the last modification time of that
-directory, as recorded by dired.
