I already have a decoder function, coded in Mathematica, based on
Appendix B of RFC-1305, which ought to work for NTPv3. The problem is
one of documentation, as RFC-1305 is pretty telegraphic, although it
does point one to the descriptions of the relevant tests.
I gather that the actual NTPv3 code does not really follow RFC-1305.
That seems to be the bottom line.
