Question

Answer 1

Just comparing two timestamps would suffice:

$t1 = strtotime($time);
$t2 = strtotime($Max_Time);

if($t1 > $t2) { .. }

Answer 2

Why don't you create two DateTime objects and compare these?

Like:

$A = new DateTime(); 
$A->setTimestamp(strtotime($time));

$B = new DateTime(); 
$B->setTimestamp(strtotime($Max_Time)); 

if ($A > $B) echo "You use if statements to compare"
