[icnrg] Fwd: New Version Notification for draft-gundogan-icnrg-ccnx-timetlv-01.txt

[Cenk Gündoğan <[e-mail]>]

Dear ICNRG,

we updated our CCNx Time TLV draft to include the following changes:

* we removed the previously included discussion on using a time base TLV
  for (absolute) RecommendedCacheTime (RCT) TLVs in content objects. The
  current approach interprets RCT as absolute (normal behavior) for UTC
  timestamps (8 octets), and as relative for a compact timestamp (1
  octet).

* we added an explicit configuration for exponent, mantissa, and bias to
  Section 4. That configuration yields a milli second resolution for
  lower time values and can also (with low resolution) reaches values
  has high as ~4 years.

* we added a few alternatives to section 5 (CCNx protocol integration)
  to provide more material for discussions. This topic needs to converge
  to a distinct solution, though.

As always, any feedback is highly appreciated.

Cheers,
Cenk
