| The very beginning of the last reference is misleading and
..coordinated-universal-time-utc.html
| wrong:
|
| "Properties of UTC
|
| The time scale UTC (Coordinated Universal Time) owes its
| existence to the CCIR (International Consultative Committee
| of Radiocommunications) of the ITU (International
| Telecommunications Union) which proposed to broadcast
| time signals worldwide in a "coordinated" way, i.e.
| by reference to a common time scale."
|
| The concept for UTC was devised by people from the BIH
| and some other metrology institutes, not by the CCIR;
| and the CCIR has never produced a time scale. It is

Hm, indeed a sloppy translation of the original german text
Die Einführung der Zeitskala UTC geht auf Vorschläge des CCIR
(Comité Consultatif International des Radiocommunications)
zurück
which is more like "Introduction of the time scale UTC originates
in suggestions made by..". And isn't that in line with Steve
Allen's sleuthing, which ends up saying
Recommendation 374 contained the details of what is now
informally referred to as the original form of UTC even though
the CCIR did not use that name.
But of course passion can't be replaced by anything else.
Maybe money?
