that is bad advice.
it is not only much more work to set up, it also doesn't remotely yield
the same results. ntpd is much much better, since it doesn't rely on a
single answer from soem server to set the clock, and because it adjusts
the clock frequency over time.
there is not much point in using rdate at all.
