Yes. The clock. Ntpdate only takes snapshots, ntpd looks how the offset
develops in trying to reduce it to zero and keeping it at zero.

Ntpd does things like observing the offset a known interval apart. If
the interval isn't reliable (because ntpdate has changed the clock in
the meantime), ntpd can't estimate trends.
