I can show you how to do a login and a logout. What does this have to do with the question about the date? I think that is a separate topic.

Here are my teaching examples of how it is done. Logout first...

<?php // RAY_logout_example.php
error_reporting(E_ALL);

// MAN PAGE HERE: http://us.php.net/manual/en/book.session.php
// ALWAYS START THE SESSION ON EVERY PAGE
session_start();

// SEE IF THE CLIENT IS ALREADY LOGGED OUT
if (empty($_SESSION["uid"]))
{

// CLIENT IS NOT LOGGED IN
    echo "<br/>YOU ARE NOT LOGGED IN \n";
    echo "<br/>CLICK HERE TO <a href=\"RAY_login_example.php\">LOG IN</a>\n";
    die();
}

// SET THE EXPIRATION FOR COOKIES
define('COOKIE_LIFE', 60*60*24); // A 24-HOUR DAY IN SECONDS ( = 86,400 )
$cookie_expires	= time() - date('Z') - COOKIE_LIFE;

// CLEAR THE INFORMATION FROM THE $_SESSION ARRAY
$_SESSION = array();

// IF THE SESSION IS KEPT IN COOKIE, FORCE SESSION COOKIE TO EXPIRE
if (isset($_COOKIE[session_name()]))
{
   setcookie(session_name(), '', $cookie_expires, '/');
}

// TELL PHP TO ELIMINATE THE SESSION
session_destroy();


// OPTIONAL - CLEAR ALL COOKIES
// foreach ($_COOKIE as $key => $value)
// {
//    setcookie($key, '', $cookie_expires, '/');
// }

// OPTIONAL - REDIRECT TO THE HOME PAGE
// header("Location: /");
// exit;


// GIVE THE CLIENT A LINK TO THE LOGIN
echo "<br/>YOU ARE LOGGED OUT\n";
echo "<br/>CLICK HERE TO <a href=\"RAY_login_example.php\">LOG IN</a>\n";

Here is the login script...

<?php // RAY_login_example.php
error_reporting(E_ALL);

// ALWAYS START THE SESSION ON EVERY PAGE
session_start();

// IF THERE IS uid IN THE COOKIE, PUT IT IN THE SESSION TO SHOW CLIENT IS LOGGED IN
if (!empty($_COOKIE["uid"]))
{
    $_SESSION["uid"] = $_COOKIE["uid"];
}

// IF THERE IS uid DATA IN $_POST, PROCESS IT HERE
if (!empty($_POST['uid']))
{
// FIRST, VOID THE SESSION VALUE
    $_SESSION["uid"] = NULL;

// IS THE UID CORRECT? - IN THE REAL WORLD THIS IS A DATA BASE LOOKUP
    $uid = trim(strtolower($_POST["uid"]));
    if ($uid == 'hello')
    {

// YES, THE UID IS CORRECT - COMPLETE THE LOGIN BY STORING THE UID IN THE SESSION ARRAY
        $_SESSION["uid"] = $uid;
    }
    else
    {

// NO, THE UID IS NOT CORRECT
        echo "<br/>WRONG UID - YOU ARE NOT LOGGED IN";
    }
}



// SEE IF THE CLIENT IS ALREADY LOGGED IN
if (isset($_SESSION["uid"]))
{
// THIS WOULD BE THE RIGHT PLACE TO SET THE COOKIE TO KEEP CLIENT LOGGED IN OVER TIME ACROSS MULTIPLE BROWSER SESSIONS
    /* SET COOKIE HERE */

// CLIENT IS LOGGED IN
    echo "<br/>YOU ARE LOGGED IN AND YOUR UID IS {$_SESSION["uid"]}\n";
    echo "<br/>CLICK HERE TO <a href=\"RAY_logout_example.php\">LOG OUT</a>\n";

// SHOW THE CONTENTS OF THE SUPERGLOBAL ARRAYS
    echo "<pre>\n";
    echo "_POST: ";    var_dump($_POST);
    echo "_COOKIE: ";  var_dump($_COOKIE);
    echo "_SESSION: "; var_dump($_SESSION);
    echo "</pre>\n";
    die();
}



// IF WE GET HERE, THE CLIENT IS NOT LOGGED IN
// DROP INTO HTML TO PUT UP THE LOGIN FORM
?>
<form method="post">
TO SIMULATE A LOGIN TYPE 'Hello' HERE: <input type="text" name="uid" />
<input type="submit" />
</form>

<?php
// SHOW THE CONTENTS OF THE SUPERGLOBAL ARRAYS
echo "<pre>\n";
echo "_POST: ";    var_dump($_POST);
echo "_COOKIE: ";  var_dump($_COOKIE);
echo "_SESSION: "; var_dump($_SESSION);
echo "</pre>\n";
