title: HTML5 time input step attribute not working in Android
body: <p>Using the following code </p>
  
  <pre><code>&lt;input type="time" step="1800"&gt;
  </code></pre>
  
  <p>Step=1800 seconds restricts the time input to 30 minute steps. This works as expected in a desktop browser. But it appears to have no effect on android (4.4.4). </p>
  
  <p>Anyone know of a solution or workaround to make this (restrict time input to 30 minute intervals) work natively in Android ? As a last resort, I can try the cordova datepicker plugin (not sure if it allows for steps), but a native html5 solution would be preferred by far.
  Thanks in advance.</p>
