	Project Vincent here at ISU uses kerberos to authenticate many of
its services, including zephyr and afs. Kerberos requires that the clients
and server be within 5 minutes, and unfortunately, some of my machines have
a terrible tendency to drift. (My Gateway pentiums will gain 5 minutes in
a week and a half sometimes.)

	NTP happens to be the one service they provide for synchronization.

	So, for purposes of kerberos, afs, and zephyr, I run ntp on all
my machines.

	Well, from a "just the fax ma'am" perspective, time syncronization of
some sort is definitely required on any distributed network, for filesystems
and authentication. And IMHO a surprising number of sites are using ntp rather
than timed-implementations, because of the fact that timed is udp-broadcast
based (and is thus limited to local networks, requiring special configuration
on gateways and routers), and ntp is server-client based, and will also
work (well) over slow/long links.

	Again, IMHO.
