Sorry my referents confused you. It is the code for chrony on ntp that
is not available (does not exist). And it is not "replacing one small

That may be true. Unfortunately the majority of the worlds computers
already have no interest in accurate time keeping because of the
architecture of the operating system. On the other hand, just as with
ntpd which was originally written for Unix type systems, someone might
decide that an ntp program which is two to three times more accurate
than ntpd, and has a much faster startup time might be useful on Windows
and be willing to invest the time and effort in the port. 
Just as with you, many people do not know about chrony to get interested
in supporting it.

Yes, and it has been taken over now by others, who have added refclock
support, IPV6 support, bug fixes in the past month or so. But noone has
stepped forward who is interested in adding windows support yet. 
Are you volunteering?
