title: Update dateTime column with laravel
body: <p>I have a pins table in my database with a pin_date column.</p>
  
  <p>In my migration I have this: </p>
  
  <p><code>$table-&gt;dateTime('pin_date')-&gt;nullable();</code></p>
  
  <p>I have a button that points to a post route</p>
  
  <pre><code>Route::post('/pins/pin-date/{id}', 'PinsController@pinDate');
  </code></pre>
  
  <p>that leads to a pinDate controller method:</p>
  
  <pre><code>public function pinDate($id)
  {
      $pin = Pin::find($id);
  
      $pin-&gt;save();
  }
  </code></pre>
  
  <p>I want to update the pin-date column in the database to the current date and time when I click the button and hit the route. I am not really sure how to do this. Any help would be greatly appreciated! Thank you!</p>
