I am sending modifications to the Argentinian time zone table...
please check comments below to find out the source used.

We did three modifications:

* The table was completed for the missing years 1989-1993.
* The name of the time zone was changed from
  America/Buenos_Aires to Argentina/Buenos_Aires
* The (short) names where changed from E%sT to AR%s (AR was
  chosen because they are the ISO letters that represent
  Argentina).
