  The word, universal, for days starting at midnight, already appears
  in the resolutions of the International Meridian Conference
  held 1884-10-01..22 in Washington DC:

      "That the Conference proposes the adoption of a universal
      day for all purposes for which it may be found convenient
      and which shall not interfere with the use of local or
      standard time where desirable"

   See [].
