Bug description:Argentina's DST setting is wrong - DST should not be applied

Description:
------------
I'm trying to troubleshoot and solve this problem: the server I'm working
on (php 5.2.9 on Linux), has the correct local time
(America/Buenos_Aires):

user@server [/home/site/public_html]$ date
Mon Nov  1 17:11:14 ART 2010

php.ini is set with date.timezone = "America/Buenos_Aires" I also tried to
set the timezone directly in the script with

<?php
ini_set('display_errors', true);
error_reporting(E_ALL|E_STRICT|E_NOTICE);

//date_default_timezone_set("America/Buenos_Aires"); 
//echo  date_default_timezone_get(), "<br>";
echo "ini: ", ini_get('date.timezone'), "<br>";

$now = date("H:i:s T I");
$nowdate = date("Y-m-d");
echo $nowdate." ".$now;
?>

but to no avail, the result is

ini: America/Buenos_Aires
2010-11-01 18:11:14 ARST 1

when it should read 17:11 (It's consistently one hour ahead).

I checked and as you can see in the code, PHP thinks it should be applying
DST, and Argentina decided to not apply it this year.

I tried dumping the timezones transition as suggested. I got the
following:
The timezone America/Buenos_Aires switches to standard time on 20 Mar 2011
@ 02:00.
The new GMT offset will be: -10800 (ART)
