title: How can I add decimal places to a TimeSpan object's totalseconds?
body: <p>I have a function which returns seconds since epoch:</p>
  
  <pre><code>public static string getEpochSeconds()
  {
     TimeSpan t = (DateTime.UtcNow - new DateTime(1970, 1, 1));
     var timestamp = t.TotalSeconds;
     return timestamp.ToString();
  }
  </code></pre>
  
  <p>It outputs, for example: <strong>1373689200.79987</strong> but for the purposes of my application, I need it to output one more decimal place digit - for example <strong>1373689200.799873</strong>. How is this possible?</p>
  
  <p>Thanks!</p>
