Your expected output does not make sense to me, because line nogad mentioned, the seconds and minutes change. Please clarify. Meanwhile here the conversion format you wanted:

$datestr = 'Wed Oct 12 14:40:50 PDT 2016';
$dt = new DateTime($datestr);
echo $dt->format("Y-m-d\ H:i:s O");

Output is:

2016-10-12 14:40:50 -0700
