 New Comment:

If I'm not mistaken the "actual results" are correct, and the 
"expected results" are wrong.  At least according to Wikipedia[1] 
America/Sao_Paulo and America/Bahia have the same offset to UTC
and identical DST offset.

If so, this is not a bug (but rather an older bug was fixed).

Description:
------------
I changed my server application before Freebsd with php 5.3.3 now Ubuntu with php 
5.3.10.
I noticed that there are differences between treatment dates in different 
timezones.

Note that when BRST "America/Sao_Paulo" advances one hour.

Test script:
---------------
<?php

error_reporting(E_ALL);

$timezone = date_default_timezone_get();
$time = mktime(12,0,0,1,15,2013);

$agoraAqui = date("d/m/Y H:i:s");
$antesAqui = date("d/m/Y H:i:s", $time);

date_default_timezone_set('America/Bahia');
$agoraLa = date("d/m/Y H:i:s");
$antesLa = date("d/m/Y H:i:s", $time);


echo "<table border=1>
	<tr>
		<td></td><td>NOW</td><td>In BRST ({$time})</td>
	</tr>
	<tr>
		<td>{$timezone}</td><td>{$agoraAqui}</td><td>{$antesAqui}</td>
	</tr>
	<tr>
		<td>America/Bahia</td><td>{$agoraLa}</td><td>{$antesLa}</td>
	</tr>
</table>
<br />
<a href='http://wwp.greenwichmeantime.com/time-zone/south-america/brazil/time-brazil/'>time-brazil</a>
";
?>

Expected result:
----------------
NOW | In BRST (1358258400)
America/Sao_Paulo | 01/03/2013 14:46:27 | 15/01/2013 12:00:00
America/Bahia | 01/03/2013 14:46:27 | 15/01/2013 11:00:00


Actual result:
--------------
Correct in:
- freebsd + php 5.3.3
- freebsd + php 5.3.6
- windows + php 5.3.8

NOW | In BRST (1358258400)
America/Sao_Paulo | 01/03/2013 14:46:27 | 15/01/2013 12:00:00
America/Bahia | 01/03/2013 14:46:27 | 15/01/2013 11:00:00

Error in:
- freebsd + php 5.3.10
- ubuntu + php 5.3.10
- windows + php 5.4.3

NOW | In BRST (1358258400)
America/Sao_Paulo | 01/03/2013 14:46:27 | 15/01/2013 12:00:00
America/Bahia | 01/03/2013 14:46:27 | 15/01/2013 12:00:00
