Hi, I am not a 6lo native, but I reviewed the draft specifically from a timestamp formatting perspective. In the NTP working group we currently have a draft in WGLC that presents guidelines for defining timestamp formats. https://tools.ietf.org/html/draft-ietf-ntp-packet-timestamps-05
I believe that the definitions of the timestamps (DT and OT) in draft-ietf-6lo-deadline-time should be more detailed. For example, aspects about the epoch and the potential effect of leap seconds are currently not described in the current draft. I would suggest to follow the timestamp specification template of Section 3 in draft-ietf-ntp-packet-timestamps-05. Thanks, Tal.
