title: How to update DateTime.Now binding purely within XAML?
body: <p>Suppose I have a <code>StatusBarItem</code> in my <code>StatusBar</code>, whose sole purpose is to display current <code>DateTime</code> information.  I know how to accomplish this from code-behind; however, I am trying to figure out a way to do it solely from XAML.</p>
  
  <p>This is the XAML code I use:</p>
  
  <pre><code>&lt;StatusBarItem Content="{Binding Source={x:Static sys:DateTime.Now}, StringFormat='dd/MM/yyyy hh:mm tt'}"/&gt;
  </code></pre>
  
  <p>It displays the <code>DateTime</code> information of when I run the program, but I can't figure out a way to update it purely through XAML, if that's even possible.</p>
