setting session time out

@noctrum: I assumed it was using php sessions, however you are correct in saying it uses cookies.
@Volkscom: I would create my session, somewhat like what I have below.

Starting the session:

Code:

function session_create()
{
    session_start();
    
    // timeout in 60 seconds
    $timeout = 60;
    
    $_SESSION['timeout'] = time() + $timeout;
}

Checking if the session has timed-out

Code:

function session_timed_out()
{
    if( time() > $_SESSION['timeout'] )
    {
        session_destroy();
        return TRUE;
    }
    return FALSE;
}

Use it like so:

Code:

session_create();

if( session_timed_out() )
{
    // do something if the session is no longer valid (timed-out)
}
else
{
    // continue the script because the user session is still valid
}
