In the new version of systemd Polkit is no longer used to request authentication from users.Ordinary users can use timedatectl to modify time without authentication，The lock button may be removed later

That can be removed if and only if no distro shipping MATE 1.26 is using an older version of Systemd. Also, what are the implications of this for distros that don't use Systemd (e.g all BSD based distros)? Note that the latter concern does not apply if mate-time-admin depends on systemd and thus is not built without it.
