Finally you want to stop the server, then just do this

$ php app/console server:stop

Possible questions:

If you get an error when executing php app/console server:run

You only need to find the AppKernel.php file under the app folder and add a method at the end of the file:

<span>    public</span> <span>function</span><span> init()
    {
        date_default_timezone_set( </span>'Europe/Paris'<span> );
        parent</span>::<span>init();
    }</span>

After saving, restart the server (php app/console server:run) and you are done.
