title: How to add a custom time picker in a Windows Phone 8.1 app?
body: <p>I have implemented time input as a length of time in my application using a textbox and parsing the string to a TimeSpan object.</p>
  
  <pre><code>//Assign text box string value to a time span variable.
  TimeSpan workTm = TimeSpan.ParseExact(wrkString, @"hh\ \:\ mm\ \:\ ss\ \:\ fff", CultureInfo.InvariantCulture);
  </code></pre>
  
  <p>But I'm wondering how I can add a time picker control like the below image to the application. I don't see any available control in the toolbox. </p>
  
  <p>Is the any custom control that I could use and how is it implemented?</p>
