title: Ionic: date pipe and local date
body: <p>I want to print creation dates for news posts. I used the date pipe of angular.</p>
  
  <pre><code>{{news.created_at | date:'shortDate'}}
  </code></pre>
  
  <p>I saw after testing on my smartphone (language: german), that the dates are in english format (e.g. 10/26/2017).</p>
  
  <p>Is there an option to format date in ionic according to the device language? </p>
