title: In Wordpress, can I use WP_Query with timestamp?
body: <p>I have code like this,</p>
  
  <pre><code>    $date_arg = array(
          'after' =&gt; array(
              'year'  =&gt; $num_days_ago['year'],
              'month' =&gt; $num_days_ago['mon'],
              'day'   =&gt; $num_days_ago['mday'],
      ),
          'inclusive' =&gt; false,
      );
      $query = new WP_Query( array ( 'date_query' =&gt; $date_arg, 'post_type' =&gt; $post_type ...
  </code></pre>
  
  <p>This is working fine but I have to specify a exact date. Is it possible to use "timestamp" to make the query.</p>
  
  <p>For example, I want to query posts that is within 24 hours. I can get the timestamp by</p>
  
  <pre><code>$ts = time() - DAY_IN_SECONDS
  </code></pre>
  
  <p>It is possible to get the posts that is created after $ts?</p>
