Re: ccnx-timetlv:  I read the draft, and I saw Cenk's presentation.
Adopting this seems fine.

A couple of minor questions/comments:

Motivation: If I understand correctly, this will reduce the size of TLVs where it is used from 12 to 5 total bytes, is that correct?

5. Protocol Integration - I believe RFC 8609 specifies how an unknown type field should be handled (ignored/skipped over).  Does it also specify how an unexpected length field should be handled?  In the comparison of the alternative approaches, it might be good to describe what should happen when a packet using the compact encoding arrives at a legacy forwarder for each approach.  If RFC 8609 does not specify what to do if a length is different than expected, perhaps that should be included with the changes.  One wonders if the parser might decide it has lost sync and throw the whole packet away...
