@defun verify-visited-file-modtime buffer
This function compares what @var{buffer} has recorded for the
modification time of its visited file against the actual modification
time of the file as recorded by the operating system. The two should be
the same unless some other process has written the file since Emacs
visited or saved it.

This function compares what @var{buffer} (by default, the

file against the actual modification time of the file as recorded by the
operating system. The two should be the same unless some other process
has written the file since Emacs visited or saved it.
