	Yes, but what does that ntp.conf look like?  Are you using 
iburst?  Any authentication?  Manually setting minpoll and/or 
maxpoll?  Did you have a good drift file to start with?

	You need to provide some more specifics before you can make an 
attempt to compare this to ntpdate.

	Not comparable.  You need to include all thirteen servers before 
this could potentially be considered comparable.
