title: retrive records where updated_at is not older than X seconds in Laravel (eloquent)
body: <p>Following the examples found here on stack overflow I'm trying to do this:</p>
  
  <pre><code>$users = User::where('updated_at', '&gt;', time() - (5))-&gt;get();
  </code></pre>
  
  <p>As the title of the post, I would like to receive only the records where the field "updated_at" is not older than 5 seconds. I also tried something like that:</p>
  
  <pre><code>...where('updated_at', '&lt;', DB::raw('(NOW(), INTERVAL 5 SECOND)'))...
  </code></pre>
  
  <p>or</p>
  
  <pre><code>...where('updated_at', '&gt;=', time() - (1*1*5))-&gt;get();
  </code></pre>
  
  <p>but keeps giving me even the obsolete records...</p>
