Tim,
A good deal of quality design time went into the statistical analysis of
errors and the manner in which statistics are presented to the
application, in this case via ntp_gettime(). You don't want to know
anything other than the carefully maintained maximum error and estimated
error statistics. Neither the stratum of the server nor the poll
interval nor the precision nor any other statistic is necessary to
evaluate the quality of time. The maximum error and estimated error
already take those factors into account. You really don't want to second
guess what the server is doing, just that it and the local client are
providing dependable statistics.
As I said in my last, your clock is Big Ben and NTP is manipulating the
number of farthings, h'apennies, pence, shillings, pounds and guineas on
the pendulum. [Gawd, after 33 years since decimalization, I'm not sure I
remember how to spell all that coinage.]

You did forget the threepence, half-crowns, crowns, and florins, all of
which I have in my collection.
I seems to remember reading somewhere that Big Ben actually uses NTP to
stay accurate.
