title: How can I get a string that shows the integer number of seconds since 1970?
body: <p>Here's what I tried so far:</p>
  
  <pre><code>var value = DateTime.UtcNow.Subtract(new DateTime(1970, 1, 1)).TotalSeconds.ToString()
  </code></pre>
  
  <p>It gives me the answer below but I would like to get a whole number:</p>
  
  <p>"1500092088.9501"</p>
