The more I reflect on this the more I realize that Nicolas Stoyko
attended and took notes on many of the astronomy/time/radio meetings
during the 1950s and 1960s.  Lots of the history of who said what when
is in the opening sections of issues of Bulletin Horaire, and detailed
in a way that is not typically found in the official proceedings.

The 1955 meetings are interesting because atomic time was a thing,
but atomic timescales were not yet a thing anyone had done, and
Ephemeris Time was a thing that a few people had done.
So in all those discussions it is clear that Universal Time is
unquestionably understood to be a measure of earth rotation.

Speaking of meetings, ITU-R WP7A meets in 10 days and looks likely to
discuss leap seconds.
