Hello Michael,

I'll appreciate if any of those wanted it; first people I've talked to
about it pointed me to T2TRG. I'll try to get a hold of the chairs on
the virtual hallways.

Does either of those have a versioned history? Without a change log in
them, and no mention of the example DOS epoch discoverable in either, I
couldn't find what was there.

(8366 has a section on clock sensitivity, but that is explicitly listing
required-verification-of-expiry, nonce-based and
never-expiring-vouchers, without touching the middle ground.)

Yes, but I think I only get away with one toy reference per document ;-)

Thanks for your points and the issue
