title: Created_at time are all same table relation in Laravel6
body: <p>I'm studying table relation in Laravel6. Here is my code which works but suddenly all records Created_at time displayed the same <code>2021-08-02 11:34:30</code>. I'm sure that time was right. but I noticed it all same. Could you teach me how to fix please?</p>
  <p>I would like to get the products table's created_at.</p>
  <pre><code>class ProductController extends Controller {
      public function index() {
          $products = Product::All();
          $products = Product::with('categori')
          -&gt;join('creators', 'creators.id', '=', 'products.creator_id')
          -&gt;join('categoris', 'categoris.id', '=', 'products.categori_id')
          -&gt;join('branches', 'branches.id', '=', 'products.br_id')
          -&gt;join('users', 'users.id', '=', 'products.user_id')
          -&gt;join('colors', 'colors.id', '=', 'products.color_id')
          -&gt;get();
          $data = array(
              'title' =&gt; 'index',
              'no'    =&gt; 1,
              'products'  =&gt; $products,
              'created_at' =&gt; created_at,
          );
          return view('product.index',$data);
      }
  </code></pre>
  <p><strong>Here is my blade file</strong></p>
  <pre><code>{{ $product-&gt;created_at-&gt;format('Y-m-d H:i:s') }}   
  </code></pre>
  <p><strong>UPDATE: Model Produt</strong></p>
  <pre><code>use Illuminate\Database\Eloquent\Model;
  
  class Product extends Model {
      protected $fillable = ['title','kansu', 'customer', 'memo', 'status', 'memo2', 'color_id', 'creator_id', 'br_id','user_id' ,'categori_id'];
  
      public function categori() 
      {
          return $this-&gt;belongsTo(Categori::class);
      }
  }
  </code></pre>
