NetBSD has been using the rdate from 4.4BSD LITE since 1.0. I'm surprised
this isn't included in FreeBSD. Also, the ntpdate command included with
xntpd is a clone of rdate.
Also, there are three versions of the NTP protocol out there. The ntpdate
command can specify version 1, 2, or 3. The server and the client have to
both be talking at the same version level or the time negotiation won't
happen. Solaris 2.4 and 2.5.x rdate talks version 3 and ntpdate also does
this as the default. I've run into some time servers that only talk version
1 and 2 of ntp. The 4.4BSD rdate seems to talk version 3.
Actually, to correct myself, the server will talk to any client that is at
or less than the rev of the server.
