The hash code is computed over only the numeric data content comprised of delta 
TAI offsets and NTP timestamps including those for validity and expiry in

This hash could also do with being upgraded and augmented for backward

commented on list regarding C 51 2016-01.

Take care. Thanks, Brian Inglis              Calgary, Alberta, Canada
