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.
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.

The IESG plans to make a decision in the next few weeks, and solicits final

Abstract
This document specifies a new type for the 6LoWPAN routing header
containing the delivery deadline time for data packets. The deadline
time enables forwarding and scheduling decisions for time critical
IoT M2M applications that need deterministic delay guarantees over
constrained networks and operate within time-synchronized networks.
