CCNx utilizes delta time for a number of functions. When using CCNx
in environments with constrained nodes or bandwidth constrained
networks, it is valuable to have a compressed representation of delta
time. In order to do so, either accuracy or dynamic range has to be
sacrificed. Since the current uses of delta time do not require both
simultaneously, one can consider a logarithmic encoding such as that
specified in [RFC5497] and [IEEE.754.2019]. This document updates
_CCNx messages in TLV Format_ [RFC8609] to specify this alternative
encoding.
