Danny,
When I first asked the Number Czar for an NTP port number circa 1980, I
purposely asked for both a UDP and TCP port, primarily to avoid the
possibility that some j-random incompatible service might be assigned
TCP port 123. Secondarily, I wanted to sustain the possibility that some
NTP monitoring function might in fact wish to use the TCP port. That
remains a possibility.
