I'm still compiling (about every two weeks or so) new versions of the
dev branch code and putting them on my server, i.e.:
http://norloff.org/ntp/dev/
and
http://norloff.org/ntp/
for the regular code which is updated less often.
The way I install ntp on new machines is to use the Meinberg installer,
then replace the actual binaries with those I've compiled myself.
I've just replaced my running version with code I compiled a few minutes
ago, it seems to behave well:
C:\install\ntp>ntpq -pnc rv
remote refid st t when poll reach delay offset
jitter

Sorry about the wrapping, the key point is that all my servers agree
that the local clock is just a ms or two off, this is pretty good,
particularly since it is less than 5 minutes since I restarted ntp.
