Well, sure we do - temporal plumbing, the distribution of time
signals through those "tubes" that Ted Stevens loves. (Unless he was
thinking the internet is driven by vacuum tubes - never thought of
that before.)

A bonanza for the vendors :–)

I'm not sure it's contradictory so much as absent data.

Maybe this new list will resolve all our difficulties. Our
statements are all converging. I'm certainly deeply skeptical that
the ITU has the authority to screw with civil timekeeping worldwide
on a whim. And whether it is obvious, I'm also very sensitive to
arguments based on pragmatic real-world constraints. Where we differ
is perhaps that I regard issues of mean solar time as being also
pragmatic and real-world.

I'm convinced that if we could focus on technical and user issues we
could start to make progress on forging a new consensus. (We can
start with an assurance that any new standards will be made publicly
available.) Having the ALHP hanging over our heads is a useless
distraction.
