Description:
------------
---
From manual page: http://www.php.net/datetime.createfromformat
---

While creating a datetime object using following function  

DateTime::createFromFormat('G:iA', '15:00PM');

produced this object

DateTime Object
(
  [date] => 2017-07-02 03:00:00.000000
  [timezone_type] => 3
  [timezone] => UTC
)

Its mixing "G/H" and "A" to produce wrong results as it adds extra hours resulting in wrong date and time. May be we should ignore "A" in case if "G/H" is used instead of "g/h"

Test script:
---------------
I think this array has all possible scenarios:

$test = [
   DateTime::createFromFormat('G:i', '3:00');
   DateTime::createFromFormat('G:i', '15:00');
   DateTime::createFromFormat('G:iA', '3:00AM');
   DateTime::createFromFormat('G:iA', '15:00AM');
   DateTime::createFromFormat('G:iA', '15:00PM');
];

print_r($test);

Expected result:
----------------
I was expecting to see object at last index with correct time like following

DateTime Object
(
  [date] => 2017-07-01 15:00:00.000000
  [timezone_type] => 3
  [timezone] => UTC
)


Actual result:
--------------
It produced following object:

DateTime Object
(
  [date] => 2017-07-02 03:00:00.000000
  [timezone_type] => 3
  [timezone] => UTC
)
