"9:10" is not time; this is a string "9:10".

Try this:

PHP

<?php
$mytime = '9:16';
$sysdate = strtotime("now");
$timediff = ($sysdate - strtotime($mytime))/3600;
if ($timediff < 6) {
    echo "less than 6 hours";
} else if ($timediff > 6) {
    echo "more than 6 hours";
} else {
    echo ('exactly 6 hours less');
}
?>
