Remember ntpdate?
If you run BSD it's there still
https://man.freebsd.org/cgi/man.cgi?ntpdate
It was also standard in my Linux distribution of Mandrake / Mandriva & early Debian
For reasons unknown I don't see it anymore.
I just needed to install it separately, 10 minutes ago. The HDD footprint is just a 150k I ask myself why was it removed?
No wonder many people permanently move to BSD. Things like this don't happen there
