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.
