Description:
------------
problems with DateTime::createFromFormat:

1) example create the date in 1970 instead of 2009
2) failed to create date object from my trying to do format: 'Y-m-d?H:i:sP'


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

//example #2 from http://il1.php.net/manual/en/datetime.createfromformat.php

$format = 'Y-m-!d H:i:s';
$date = DateTime::createFromFormat($format, '2009-02-15 15:16:17');
echo "Format: $format; " . $date->format('Y-m-d H:i:s') . "\n";


//my trying to create from DateTime::RFC3339 format


$dt = new DateTime(null,new DateTimeZone('gmt'));
//$time = $dt->format(DateTime::RFC3339);
$time = $dt->format('Y-m-d\TH:i:sP');
echo $time."\n";

$dt = DateTime::createFromFormat($time, 'Y-m-d?H:i:sP');
//$dt = DateTime::createFromFormat($time, DateTime::RFC3339);

var_dump($dt);

Expected result:
----------------
1) Format: Y-m-!d H:i:s; 2009-02-15 15:16:17
2) not false in var_dump($dt);

Actual result:
--------------
1) Format: Y-m-!d H:i:s; 1970-01-15 15:16:17
2) DateTime object dump
