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.
