title: Laravel 5 query builder and NOW() for date comparison
body: <p>My database (MySQL) has a timestamp field for <code>created_at</code>.</p>
  
  <p>I have two entries, with the timestamps as follows: </p>
  
  <ul>
  <li>2017-12-12 18:25:00</li>
  <li>2016-10-02 18:00:00</li>
  </ul>
  
  <p>Today is 2016-10-19 (for future reference). If I use the following query, I get no results:</p>
  
  <pre><code>    $job = $jobs-&gt;where('closing_at', '&gt;=', 'NOW()')
              -&gt;orderBy($sorter[0], $sorter[1])-&gt;paginate(24);
  </code></pre>
  
  <p>If I hardcode the date, I get the correct results, just the one future date:</p>
  
  <pre><code>    $job = $jobs-&gt;where('closing_at', '&gt;=', "2016-10-19 00:00:00")
              -&gt;orderBy($sorter[0], $sorter[1])-&gt;paginate(24);
  </code></pre>
  
  <p>I'm assuming my error is in the use of <code>NOW()</code> with the Eloquent query builder but I can't figure out the correct way to use this is. </p>
