title: Pintrest recipe rich pins cook time not showing
body: <p>I am having issues getting pintrest to pick up my dt-duration value on my web page.</p>
  
  <p>I am using the h-recipe microformat method which pintrest support.</p>
  
  <p>I've used the examples they provided on pintrest and microformat:

  <a href="https://developers.pinterest.com/docs/rich-pins/recipes/" rel="nofollow noreferrer">http://microformats.org/wiki/h-recipe#Example</a></p>
  
  <p>My current attempt:</p>
  
  <pre><code>&lt;time class="dt-duration" datetime="15M"&gt;15 minutes&lt;/time&gt;
  </code></pre>
  
  <p>All my other formats are getting picked up except for this. I feel I might be formatting this wrong but I cant find any where on my web search for acceptable format.</p>
