   An excellent account of the political and technical history of UTC is on
   Steve Allen's page [http://www.ucolick.org/~sla/leapsecs/timescales.html#UTC].
   For instance, it tells us that official use of the term "UTC" dates from 1964.

   The informal term "UTC with rubber seconds" is intended to refer to the time
   when the rates of UTC and TAI differed (before TAI reached 1972-01-01 + 10 s).
