Maybe my copy of emacs 26 is too old.
If the visited file doesn’t exist, return -1.
If the visited file is deleted by external program, then does it return -1?

In my copy of Emacs 26, it says
If the visited file doesn’t exist, return -1.
Which is exactly what it does. *scratch* and *Messages* do not visit
files, so they have no recorded modtime, hence 0. If you visit a new
file but don't save it, you get -1.
