Description:
------------
Hi

There seem to be a discrepency for timezones names as reported by timezone_abbreviations_list() and the DateTime object parser. We have found a (small) numbre of timezones for which this happens:

Been reported and reproduced with PHP 5.1.41 adn PHP 5.2.13



Test script:
---------------
1 - Get identifiers list:

$all = timezone_abbreviations_list();

The resulting array contains, for instance:

[54] => Array
  (
    [dst] => 
    [offset] => 36000
    [timezone_id] => Australia/NSW
   )
2 - Use this timezone_id to create a DateTimeObject

$dateString = "2010-05-15 00:00:00 Australia/NSW";
$date = new DateTime( $dateString);



Expected result:
----------------
A DateTime object created

The above code runs without problem if timezone identifier (Australia/NSW) is replaced by Australia/Nsw.

I have found the following timezones to have the same issue:
Australia/ACT
NZ-CHAT
America/Know_IN
Australia/LHI
Chile/EasterIsland
Europe/Isle_of_Man

In others, all timezones names that do not follow camelcase strictly. There are probably others.

Actual result:
--------------
Fatal error: Uncaught exception 'Exception' with message 'DateTime::__construct() [datetime.--construct]: Failed to parse time string (2010-05-15 00:00:00 Australia/NSW) at position 20 (A): The timezone could not be found in the database' in /XXXX/test.php on line 4
