  | By the way, I use Ubuntu Hardy (maybe you already fixed the tzdata but
  | Ubuntu didn't pick it).

The current tzdata seems to say that the start date should be the
first Sunday on or after the 15th (the 3rd Sunday in October.
This year, that is the 19th.)   I am not sure if we are certain that
"3rd Sunday" is correct, but Oct 19 2008 seems to have been intended.

You can fetch the current tzdata from

(or from )

Assuming your system providez the zic command, you should be able to
convert the southamerica file in the tzdata distribution into the
zone files for all the South American zones, including all of those
for Argentina.  Beware that there will soon be another update to
deal with recent changes in Brazil.

If you don't have zic (in /usr/sbin most likely) then you can also
fetch the sources:
is the most recent (or from the similar path at, build
that, and use the zic contained there - but only do that as a last resort,
and test the zone files produces from that zic before installing them to
ensure they're compatible with your libc routines.
