title: How to use published_date - Method in Telegram's instant view API?
body: <p>I am trying to setup an <a href="https://instantview.telegram.org/docs" rel="nofollow noreferrer">Instant View</a> for a website. Everything's working fine, except the published_date aspect. As I found it, it needs an div-container (or similar) with date information. Than it has to be transformed to unixtime timestamp via "@datetime(-2): xpath_query". but how do I continue? </p>
  
  <p>i.e:</p>
  
  <p>I tried: </p>
  
  <pre><code>&lt;div class="Date"&gt;19.05.2017&lt;/div&gt;
  $date: //div[has-class("Date")]
  @datetime(-2): $date
  published_date: $@
  </code></pre>
  
  <p>but this has no effect on the date. What am I doing wrong? The telegram manuel is too brief. </p>
