      Catherine Fennell hopes that 'we will soon see the US formally switch to
      international notations sometime soon'. The really old news is that the US
      has *already* officially adopted the ISO standard under ANSI X3.30 as well
      as under the NIST FIPS 4-1 standard. It is now also the default date
      standard of the US military, and used in long format as '2000-May-26' by
      them. US companies like IBM have already adopted it, long ago, as part of
      the fix for the Year 2000 Problem. It is also used on sites like
      <http://ftpsearch.lycos.com/>. It already comes as the default standard of
      the Internet as defined by both Internic and the World Wide Web Consortium
      (W3C), though the old email standards have yet to be updated to reflect this.

      As far as the old US notation of 'Month/Day' goes, the ISO format retains
      this. The ISO format merely changes the Year from two digits to four digits,
      whilst moving it from being the last item to being the first item. So,
      '12/31/00' is rewritten as '2000-12-31'. It is much more difficult for
      European people to make the change, as they have to flip the whole date end
      to end: '31/12/00' changing to '2000-12-31' or '2000-Dec-31'. As Yifan Ji
      hints, confusion will reign supreme the day after '01/01/01', as this is
      written as '01/02/01' in some countries, as '02/01/01' in others, and
      '01/01/02' in yet others. So what date is '03/05/02' for example? As the
      Internet is very much an international medium, International Standards are
      the way to go.

      Astronomers all round the world have already used the equivalent of the ISO
      format for well over 200 years, so the ideas used in ISO 8601 are certainly
      not new. Now is the time to make the change....
