What do you mean by "military" time? People seem to be confused here. Is the expected output to be as you state `3:30`, or `0330`? 0330 when literally spoken is just that "oh three hundred", but "three thirty" is another animal. What is the source of the data also? — Funk Forty Niner, Apr 13 '18 at 00:18

Assuming your times are strings in the form HH:mm, this will work:

$in = new DateTime('22:00');
$out = new DateTime('01:30');
// if in is > out, assume out is on the next day
if ($in > $out) $out->add(new DateInterval('P1D'));
$diff = $out->diff($in);
echo $diff->format('%H:%i');
