It does seem like a blunt way to affect `time-stamp`.

Maybe the time-stamp package should instead provide a prefix command
`time-stamp-inhibit` which makes the next call to `time-stamp`
do nothing.

Or a more hackish way would be for `time-stamp` to consult
`current-prefix-arg`, so as to disable the update of the time stamp when
you do `C-u - C-x C-s`.
