Laravel cookie session lifetime

Question

I used my Laravel as a OAuth2 client, and I need to keep token i cookies. So, I set driver to cookie and keep default value for lifetime 120

When any user check remember me on login, I tried to change lifetime with code:

    $lifetime = time() + 60 * 60 * 24 * 365;// one year
    Config::set('session.lifetime', $lifetime);

But without success. In any another controller I checked value of lifetime and every time I get default value.

\Log::info(\Config::get('session.lifetime'));

Edit #1:

It is enough?

if(Input::has('rememberMe')) {
   $lifetime = time() + 60 * 60 * 24 * 365; // one year
   Session::put('Expires', $lifetime);
}

Edit #2:

I put acess_token key on the same way as Expires in example above, like:

public function signin() {

    /**
     * Code for getting *client_code* and *client_state* from API server
     */

    $access_token = $this->provider->getAccessToken('authorization_code', $form_data);

    // $access_token is object and contain all data (access_token, refresh_token, expires)
    Session::put('access_token', $access_token);
    Session::put('refresh_token', $access_token->refreshToken);
    Session::put('token_expires', $access_token->expires);

    if(Input::has('rememberMe')) {
       $lifetime = time() + 60 * 60 * 24 * 365; // one year
       Session::put('expires', $lifetime);
    }


    return Response....

}

This is the 'default' Laravel session (I changed driver from file to cookie in /app/config/session.php). I know life time should be set in /app/config/session.php file, but as you can see I need longer life time for Remember me option

Actually when you are setting the value like this in a Controller:

$lifetime = time() + 60 * 60 * 24 * 365;// one year
Config::set('session.lifetime', $lifetime);

It's not updating the value in the file, instead it sets it for the current request only (in memory) and when you check the value using this from another Controller/Request like this:

Config::get('session.lifetime');

You are getting the value from the original value from file system. It's mentioned in the documentation as given below:

Configuration values that are set at run-time are only set for the current request, and will not be carried over to subsequent requests.
