ntpd uses the NTP protocol to *keep* your clock in sync with NTP servers by "drifting" the clock in tiny increments, but will not adjust the clock beyond certain (small) amounts. If the time is too far out of whack with the servers it won't do its job.
ntpdate sets the clock to the time specified by the server in one big jump allowing ntpd do to its thing.

Ok, I got the general Ideea, but only one issue remains:
the ntpdate service/daemon [/etc/init.d/ntpdate] does the "general sync"... when it starts up? or at a predefined time interval [in the case that the service is started]?
