Thanks for the pointer.  Has anyone been able to confirm what actually
happened in San Luis on Monday (January 21) at 00:00?

Also, my Spanish is pretty bad.  Were they intending to change to
UTC-03 for the whole year (as Microsoft suggests), or are they
changing to UTC-04 in winter, UTC-03 in summer?  The Babelfish
translation of the above article suggests the latter, since it keeps
talking about the "time zone".  In particular this quote:

   El huso horario que corresponde a nuestra Provincia es el que se
   encuentra al oeste del meridiano que pasa por la provincia de
   Córdoba. En ese origen se encuentra la diferencia del huso horario
   que pasa por la ciudad de Buenos Aires que es un huso horario que
   tiene una hora de diferencia

Before 1920, Argentina used what I've dubbed "Cordoba Mean Time",
which was (according to Shanks) UTC-4:16:48; surely they are not
intending to revert to _that_!
