While I think too that clockspeed is a nice thing,
50 ms accuracy is well within what an IBM compatible
personal computer with a non-realtime operating system
If you believe a PC would ever get more accuracy,
for example ten milliseconds, you've been tricked.

You might consider asking Henning to put a
new keyword 'standalone' into /etc/ntpd.conf,
specially for configurations e.g. with no
internet access, or a different means of being
synched (taiclock, *hint hint*). I vote for it.
