title: How to update visually a live tile every minute of a Windows Store App in JS/HTML/CSS?
body: <p>I would like the live tile of my app to be updated everytime the user opens the Start screen as its  live tile's feature is &quot;only&quot; visual (doesn't need to be on lockscreen or perform specific logic <em>in the background</em> for example)</p>
  <p>On the windows Store you can find &quot;watches&quot; app which will show you the time on the start screen via their app live tile usually with a granularity of every minute not more. This would be perfect for me.</p>

  <p>Those apps seems to have then a much more precise time interval than those famous 15 minutes, and they do run as a background task (those apps ask for the permission to).</p>
  <p>So what does actually happen every 15 minutes? How come those tiles are not constrained to this 15 minutes interval? I heard they might use a notifications queue, but they still need to be updated on 1 minute basis...</p>
  <p>Thanks a lot for help!</p>
