title: How can I format DateTime to web UTC format?
body: <p>I have a DateTime which I want to format to "<code>2009-09-01T00:00:00.000Z</code>", but the following code gives me "<code>2009-09-01T00:00:00.000+01:00</code>" (both lines):</p>
  
  <pre><code>new DateTime(2009, 9, 1, 0, 0, 0, 0, DateTimeKind.Utc).ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffzzz")
  new DateTime(2009, 9, 1, 0, 0, 0, 0, DateTimeKind.Utc).ToUniversalTime().ToString("yyyy'-'MM'-'dd'T'HH':'mm':'ss'.'fffzzz")
  </code></pre>
  
  <p>Any ideas how to make it work?</p>
