title: C# DateTime to UTC Time without changing the time
body: <p>How would I convert a preexisting datetime to UTC time without changing the actual time.</p>
  
  <p>Example:</p>
  
  <pre><code>DateTime dateTime = GetSomeDateTime(); // dateTime here is 3pm
  dateTime.ToUtcDateTime() // datetime should still be 3pm
  </code></pre>
