Hello ICNRG,

as discussed at [last week's ICNRG meeting](https://datatracker.ietf.org/meeting/113/session/icnrg), we are considering to adopt [draft-gundogan-icnrg-ccnx-timetlv](https://datatracker.ietf.org/doc/draft-gundogan-icnrg-ccnx-timetlv/) as a RG work item.

**Title**: Alternative Delta Time Encoding for CCNx Using Compact Floating-Point Arithmetic

**Abstract:**
CCNx utilizes delta time for a number of functions.  When using CCNx
in environments with constrained nodes and/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 [IEEE.754.2019].  This document updates _CCNx messages
in TLV Format_ (RFC8609) to specify this alternative encoding.

* [Cenk's presentation from last week](https://datatracker.ietf.org/meeting/113/materials/slides-113-icnrg-alternative-delta-time-encoding-for-ccnx-01)
* [draft-gundogan-icnrg-ccnx-timetlv](https://datatracker.ietf.org/doc/draft-gundogan-icnrg-ccnx-timetlv/)

Please let us have any feedback (support, doubts etc.) until end of next week, i.e., Friday, 2022-04-08.

Thanks,
Dirk and Dave
