Hi,

No, ntpdate gets the time from a time server and sets the
clock to the time it just received from the server, no matter
how much the difference is.
ntpd (or xntpd) behaves like you described it.
In the rcscript for ntpd first ntpdate is called once to set the
correct time during the boot process, then ntpd is started to
keep the time up to date.
If you have a running system with a big time difference, and
you want to correct it slowly and not at once, do NOT start
ntpd using the rcscript, but start it manually (see which
command they use in the rcscript in the "start" section).
Bye
Uli
