Looking in CVS, I don't see any defaults for the servers for ntpdate or
ntpd to use. It is probably a VERY good idea to recommend in the man
page and, maybe, UPDATING, that iburst be used as an option on the
server declarations in ntp.conf. This will GREATLY enhance startup time.

server iburst

It's also worth noting that the use of either numeric IP addresses or
'-4' in ntp.conf is important. If ntp sees an IPv6 address, it will only
use that address, even if IPv6 is not available. (In other words, it
won't work!)
