This site (with pointers from www.ntp.org) advertises various public and
regional time servers.  Ideally you should synchronize *one* machine to
the public servers, and internally sync to your local
source.  Note that stratum 1 servers are often closed, regional, and/or
require permission to access.  Many stratum 2 servers are available.
Depending on the number of local machines you will be synchronizing, you
may be able to access some stratum 1 servers.

Locally we synchronize one router with an accurate clock and internal
calendar (a cisco 7500) to several public stratum 1 servers.  They
follow the full NTP synch protocol.  We then have other routers that
sync to this one as peers.  Our servers then use the routers as their
time source (ntpdate on unix/linux and HP3000, freeware Dimension4 on
Win95/98/NT).

It isn't good netiquette to sync multiple servers, particularly the
typical desktop, to a public, high-stratum server.
