[PHP-BUG] Bug #51393 [NEW]: DateTime::createFromFormat() fails if format string contains timezone

From:             
Operating system: Linux
PHP version:      5.3.2
Package:          Date/time related
Bug Type:         Bug
Bug description:DateTime::createFromFormat() fails if format string contains timezone

Description:
------------
I was trying to process Apache logfiles with PHP. The default LogFormat
timestamp
%t translates to '[d/M/Y:H:i:s O]' in date() notation.
PHP fails to create DateTime instances if the format argument contains
timezone
placeholders like O P e

I am aware of the 3rd parameter of DateTime::createFromFormat() to pass
timezone
information. 
- the documentation says 'Format accepted by date()'
- DateTime is supposed to help parsing datetime formats, not to restrict

Test script:
---------------
$dt = DateTime::createFromFormat('[d/M/Y:H:i:s O]', '[13/Mar/1969:23:40:00
+0100]');
print($dt->format('c'));

Expected result:
----------------
1969-03-13T23:40:00+01:00

Actual result:
--------------
Fatal error: Call to a member function format() on a non-object
