Hi,

Based on the emails the last weeks, I think there is need for one more
update before IETF last call.

When it comes to the IETF-types review I have put in a note that I will
do that during IETF last call.

However, the section 3.3 still misses one point. Namely, information content delivered by an FDT instance can be acquired out-of-band, also. This does not remove the need to emphasize relative higher reliability protection for FDT delivery but means that there are other ways than the ones stated, including out-of-band methods. As out-of-band methods are out of scope of the spec, it would be sufficient to mention these in one sentence.

It seems that this should be updated in the text before IETF last call.

After all it is about sophisticated deduction of target epoch, not about implementation of NTPv4 (that's why I do not see it as normative).      

It is in the grey zone, but I don't think there will be any issues with
using an informational reference in this case.

To my recollection this is where ALC ended up.

Now I see big changes again in -08 vs. -07. Can you highlight what was changed and verify that the legal statements are up to date?

The changes may look bigger than they are. First of all there has been a
change in order of the statements. Secondly, it does contain the
appropriate disclaimer due to old copyright. So to me it appears to be
correct.
