20th may, Historical date!

[Richard Guy]

A little over 30 years ago, almost all nations
agreed (when else has this happened? --
over the postal system, perhaps -- not over
copyright ?) on the (adoption and) use of
the ``metric system''.

I quote from the Metric Style Guide:

   For example, April 7, 1975, is
   expressed as 1975 04 07.
   Alternative ways of writing this
   numeric date are 1975-04-07 or
   19750407.

Times can be appended, using the 24-hour
clock.          R.
