I doubt that it needed to operational and badly wrong. Ie, if it is
misbehaving so badly, debugging is only option.

Sorry, but I have always found this to be a complete copout. You can
keep the complainer busy till doomsday trying out different version and
different configs. Do you know that others have had this person's
problem? Do you know thatthe latest version fixes them? Otherwise you
are simply sending him on a fishing expidition.
ntpd being 6 days out and claiming it is on time is such a HUGE bug,
that others would have reported it and it does not sound like the kind
of bug that would be fixed by accident.

I certainly agreee with that suggestion. And it may be his problem,
although I thought that the local clock was dumped to the bottom of the
heap if there are other servers.

I think you mean "If your ssytem always needs to be up and present time
to other computers it serves, use the orphan mode"
