You can control the session timeout using

'timeout' => 3600*4, //session expire

'session' => [
    //'class' => 'yii\mongodb\Session',
    //'class' => 'yii\web\Session',
    'class' => 'yii\web\DbSession',
    'writeCallback' => function($session)
    {
        return [
            'user_id' => Yii::$app->user->id,
            'agent' => Yii::$app->request->getUserAgent(),
            'ip' => Yii::$app->request->getUserIP(),
            //'auth_key' => Yii::$app->security->generateRandomString(),

            'timeout' => 3600*4, //session expire

        ];
    }
],

Timeout is defined in session. not in writeCallback

Except as a field in the database. This will not work as "session expire".

'session' => [
    //'class' => 'yii\mongodb\Session',
    //'class' => 'yii\web\Session',
    'class' => 'yii\web\DbSession', 
    'timeout' => 3600*4, //session expire
    'writeCallback' => function($session)
    {
        #code .... Database field
    }
],
