title: Format date with Elixir
body: <p>I'm trying to format the Timex module to look a certain way. I'm trying to get today's date. but I want it formatted like this:</p>
  
  <p>2017/12/12.</p>
  
  <p>year/mn/day</p>
  
  <p>In ruby I would go to the strftime class but I'm not sure how to do this with Elixir:</p>
  
  <p>Current attempt:</p>
  
  <pre><code>Timex.local =&gt; #DateTime&lt;2017-12-12 19:57:17.232916-05:00 EST America/Detroit&gt;
  </code></pre>
  
  <p>How can I take that and format it how I specified?</p>
