Thanks, David, I though that might be the case. The systems are already
running quite a small minpoll, and I'm not sure I want to reduce it
further (to be kinder to the servers involved).
It's a pity that someone has not ported chrony to Windows, as that's the
platform where I need it. I guess they might need to add some of the
interpolation code as well. An end-node, client-only port (no ref-clock)
would be fine.
