scale of a nation, and even where it introduced a new, potentially
ambiguous notion of origin of longitude for civil mapping.

s could still save
us". Nevertheless, my impression is that the situation will likely
occur if one side decides to stop all the clocks of the other side
first. In that case both international agreements and the fact that
I've hung tapes on a radio telescope that times pulsars seem moot.

I allow that there are valid reasons for pursuing research into
visibility of the hilal and monotonic time scales for telecomms,
navigation, etc., but I don't see that either of these justify
modifications to the characteristics of civil time.

Wherein point 4 indicates that they had not yet figured out
exactly how the scheme was going to work. Point 6 requested
that the document be transmitted to, among other places, the IAU,

It's less than a week until WP7A meets, and the list of contributions
regarding UTC looks interesting

France is in there twice!

s. how many would work if recompiled?
If the ITU-R cannot find a unilateral stance then it may be time to
start thinking compromise.
Is getting the leaps out of the system's time_t worth the other hassle?
