man ntpdate

        ntpdate - set the date and time via NTP

        Disclaimer:  The  functionality of this program is now available in the
        ntpd program. See the -q command line option in the ntpd - Network Time
        Protocol  (NTP)  daemon  page. After a suitable period of mourning, the
        ntpdate program is to be retired from this distribution

        ... it is important to note that ntpdate with contrived cron scripts is
        no substitute for the NTP daemon, which uses  sophisticated algorithms
        to maximize accuracy and reliability while minimizing resource use.
        Finally, since ntpdate  does  not  discipline  the  host clock frequency
        as does ntpd, the accuracy using ntpdate is limited.

Why are you avoiding using ntpd?

man ntpd

        ... once the clock has been set, it very rarely strays more than 128 ms,
        even under  extreme  cases  of  network path congestion and jitter.
