Incidentally, what he's done is to run together the peers information
from many machines, so there is only one CDMA source. On the other
hand, it doesn't look like it is a CDMA appliance, or if it is, it has
been badly implemented, as I would not expect to see a local clock
driver on an appliance device.
The delays are rather large for the paragon of perfection of a network
that was described.
He probably needs to be aware that normal applications on the Windows
boxes will see times with a resolution that is rather poorer than can be
seen by ntptrace, as ntptrace takes advantage of the ntpd tick
interpolation, but normal applications will see times with a resolution
of one clock tick.
