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 
compatibility by possibly detached sha2/sha3 sum and/or gpg2 signature.

My off list comments were made to ObsPM regarding C 50 2015-07 and we all 
commented on list regarding C 51 2016-01.
