Description:
------------
---
From manual page: http://www.php.net/datetime.construct#refsect1-datetime.construct-description
---

Creating a DateTime from a string in the ISO8601 format "2011-12-06T19:55:34Z" will succeed, but with a DateTimeZone with name "Z". That is incorrect, since "Z" is the way to specify UTC in that ISO format.

Furthermore, if you want to create a DateTimeZone("Z") it will throw.

Best regards, hope this helps to make php better :)

Test script:
---------------
$dt = new DateTime("2011-12-06T19:55:34Z");
$tz = $dt->getTimeZone();
echo $tz->getName();



Expected result:
----------------
"UTC"

Actual result:
--------------
"Z"

Thank you for taking the time to report a problem with PHP.
Unfortunately you are not using a current version of PHP -- 
the problem might already be fixed. Please download a new
PHP version from http://www.php.net/downloads.php

If you are able to reproduce the bug with one of the latest
versions of PHP, please change the PHP version on this bug report
to the version you tested and change the status back to "Open".
Again, thank you for your continued support of PHP.

Timezone "Z" is the same as "UTC", so it's not really wrong. Newer versions of PHP do support (PHP 5.6 at least):

$dt = new DateTimeZone("Z");
