You are confusing rdate and ntp.

rdate is port 37 (tcp and udp), typically disabled as a DoS on the
machine running the reference can be had easily.

ntp runs on port 123

rdate (traditionally) does not even speak the protocol of ntp.

Why would you have rdate vs ntp installed on the one machine? Is it a
commercial UNIX? If not, install ntpdate and ntp.

BTW, rdate is referenced here: http://www.faqs.org/rfcs/rfc868.html

Where as ntp v3 is here: http://www.faqs.org/rfcs/rfc1305.html

and snto is here: http://www.faqs.org/rfcs/rfc2030.html

They are related but not interchangeable *UNLESS* you have a time-client
the does both or more.

Use ntp anyway.
