Yes :-)

You should run a binary compare to
/usr/share/zoneinfo/America/Argentina/Buenos_Aires ... in a terminal:

$ cmp /etc/localtime /usr/share/zoneinfo/America/Argentina/Buenos_Aires

if it is silent, it's OK (they're identical)

quick and dirty NO WARRANTIES:

login to an account with administrator rights

1) backup the registry (just in case)

2) download ms-tz-argentina-2008-10-16.reg from
(this is a copy I made from the tzupdate.reg referred in MS's pdf

3) double-click on it and it will ask if you are sure you want to modify
the registry, say yes (you have a backup anyway, right?

4) double click on the clock in the systray, the "set date and time"
window will open

5) select the "time zone" tab

6) choose "(GMT-03:00) Buenos Aires"

7) make sure the "adjust dst" (or whatever it's called) checkbox in that
window is CHECKED

8) press OK

that should be it (no need to reboot).

I don't know anything about this... the pdf speaks quite a lot about
handling outlook which, since I don't use I didn't care... at least
*you* should read the instructions and try to make some sense of it...
