have agreed to an "Unsegmented" CCSDS format, I suggest that we also
agree to all use the 1958 epoch as our basis, and 4 bytes of course time (since
you need that many bytes to properly contain the number of seconds since Jan 1,
1958).</span></font></p>

Jan 1, 1970 epoch in Unix just add 378691200 and you will have the number
of seconds since Jan 1, 1958. Correct me if I am wrong.</span></font></p>
