Description:
------------
I have 4 servers all of then are setup to a time zone with daylight saving and I can see that on console but php says the server is not in daylight saving time.
If I execute the command (date +"%z %Z") I get the result "-0200 BRST" and thats right because we are currently on daylight saving time what make my time zone pass from "-0300" to "-0200" but PHP doesn't see that and that happen on all my linux servers.

Reproduce code:
---------------
echo date_default_timezone_get() . "<br>";
echo date("d.m.y H:i I T") . "<br>";
$localtime_assoc = localtime(time(), true);
print_r($localtime_assoc);


Expected result:
----------------
America/Sao_Paulo
18.10.07 17:39 1 BRST
Array ( [tm_sec] => 53 [tm_min] => 39 [tm_hour] => 17 [tm_mday] => 18 [tm_mon] => 9 [tm_year] => 107 [tm_wday] => 4 [tm_yday] => 290 [tm_isdst] => 1 ) 

Actual result:
--------------
America/Sao_Paulo
18.10.07 17:39 0 BRT
Array ( [tm_sec] => 53 [tm_min] => 39 [tm_hour] => 17 [tm_mday] => 18 [tm_mon] => 9 [tm_year] => 107 [tm_wday] => 4 [tm_yday] => 290 [tm_isdst] => 0 )
