Description:
------------
The function DateTime::createFromFormat('z Y', "59 2016") return false values if there is a leap year.
I can't check it with DateTime::createFromFormat('z', "59"), because the leap year is next year, maybe than it's ok - but I don't think so.

This bug is reported earlier, but till now not fixed.

Test script:
---------------
$date = DateTime::createFromFormat('z Y', "58 2016");
echo $date->format('j. M. Y')."<br>"; // Result: 28. Feb. 2016
						
$date = DateTime::createFromFormat('z Y', "59 2016");
echo $date->format('j. M. Y')."<br>"; // Result: 1. Mar. 2016

$date = DateTime::createFromFormat('d m Y', "29 02 2016");
echo $date->format('j. M. Y')."<br>"; // Result: 29. Feb. 2016

$number = cal_days_in_month(CAL_GREGORIAN, 2, 2016); // 29
echo "$number";

Expected result:
----------------
28. Feb. 2016
29. Feb. 2016
29. Feb. 2016
29
