title: Making html5 input field of type "datetime-local" compatible with Firefox
body: <p>I'm using some of the HTML5 date and time input fields in AngularJS based interface: </p>
  
  <pre><code>&lt;input type="datetime-local" ng-model="event.date_time.start" /&gt;
  &lt;input type="week" ng-model="event.date_time.start" /&gt;
  </code></pre>
  
  <p>I need to make this interface compatible with Firefox which does not support these types of input fields.</p>
  
  <p>Is it the best to detect browser through JavaScript and display different fields accordingly or is there a way to make it compatible?</p>
