There are several cron/crontab implementations, none of which
maintained by the GNU project AFAIK. See
https://en.wikipedia.org/wiki/Cron#Modern_versions

If on a Debian GNU system or derivative, you can check which
implementation your contrab comes from with:

$ dpkg -S "$(command -v crontab)"
cron: /usr/bin/crontab
$ apt-cache policy cron
cron:
