I think there are several groups of people syncing clocks who are distinguished
by their desired level of accuracy. Comments like the above are from an
extremum group, who desire sub-millisecond accuracy. This group is needed to
further clock research, but I personally don't think such accuracy is needed
for daily operations. I'm willing to be proved wrong, however.
Here we run 4.1.1 and seem to be keeping time to the 10-20 millisecond level
with little problem. If you are happy with this accuracy, do it and don't
worry. If you are not happy, and you know who you are, worry.
