Nascondere un form per un tot di ore

[frankyster]

ciao vi spiego in poche parole cosa vorrei fare,ho un form di questo tipo:



vorrei che dopo aver cliccato sul bottone "clicca qui per confermare la tua iscrizione" il form rimanga nascosto per un tot di ore, ad esempio 12 ore, prima di ricomparire.
Qualcuno sa indicarmi come modificare il codice sotto per avere questa modifica?Grazie

<? include('header.php'); ?>

<?

if (isset($_POST["username"])) {

require ('config.php');


$sql = "SELECT * FROM tb_users WHERE username='$user'";
$result = mysql_query($sql);        
$row = mysql_fetch_array($result);

$user=$_COOKIE["usNick"];
$username = $row["username"];
$email = $row["email"];
$ip = getRealIP();

$sponsor = $_POST["sponsor"];
$status = $_POST["status"];
$date = $_POST["date"];
$amount = $_POST["amount"];
$confirm = limpiar($_POST["confirm"]);


$query = "INSERT INTO tb_offers_cronology (username, email, sponsor, amount, date, confirm, status, ip) VALUES('$username', '$email', '$sponsor', '$amount', '$date', '$confirm', '$status', '$ip')";
mysql_query($query) or die(mysql_error());
