How to save the date without UTC, but just according to the current timezone?

Question

Yii

I use the extension to mongo, I do it like this now

$collection = Yii::$app->mongodb->getCollection('visitors');
        
        $collection->insert([
            'created_at' => new UTCDateTime(round(microtime(true) * 1000)),
            'user_ip' => Yii::$app->request->userIP,
        ]);
