title: timespan between now and past datetime
body: <p>I want to calculate how much time elapsed between a datetime and now in minutes.
  This is what I have:</p>
  
  <pre><code>TimeSpan SinceStatusChange = new TimeSpan();
  SinceStatusChange = (double)(DateTime.Now.Date - StatusDateTime).TotalMinutes;
  </code></pre>
  
  <p>Basically, I'm looking to write this conditional statement:</p>
  
  <pre><code>if (SinceStatusChange is greater than 180 minutes)
  </code></pre>
  
  <p>How do I write the line "SinceStatusChange = " so I can later test if the value is greater than 180?</p>
  
  <p>Thanks.</p>
