Try something like this... Check the DateInterval class for more details.

$last = isset($_SESSION["last"]) ? new DateTime($_SESSION["last"]) : new DateTime("now");   
$now = new DateTime("now");
$diff = $last->diff($now);
if($diff->i < 2){
    $_SESSION["last"] = new DateTime("now");
    echo "SERVER IS BUSSY. TRY AFTER 2 MINUTES";
    exit();
}else{
    $_SESSION['last'] = new DateTime("now");
    echo "Continue with form data";
}
