Description:
------------
---
From manual page: http://www.php.net/datetimezone.construct
---

The documentation states that the DateTimeZone constructor accepts 'One of the supported timezone names(http://php.net/manual/en/timezones.php).' 

However, it also appears to accept offset values. Unsure if this is expected but undocumented behaviour, or a bug. In PHP 5.5.9 this throws an exception. 

Test script:
---------------
var_dump(new DateTimeZone('+0200'));

Expected result:
----------------
Uncaught exception 'Exception' with message 'DateTimeZone::__construct(): Unknown or bad timezone (+0200)'

Actual result:
--------------
object(DateTimeZone)#1 (2) {
  ["timezone_type"]=>
  int(1)
  ["timezone"]=>
  string(6) "+02:00"
}

timelib (which PHP uses) explicitly supports offset notation in addition to the usual named timezones; see the "tzcorrection" format in
  http://php.net/manual/en/datetime.formats.time.php

@requinix Makes sense. Think this needs a little update to the docs to clarify this though!

Supporting "+02:00" and the like, is new functionality since PHP 5.5. PHP 5.4 and earlier did not support this. We simply forgot to add this to the documentation.
