title: TimeZoneInfo.ConvertTimeToUtc issue
body: <p>We had an issue where one developer creates the below code and it works on his DEV environment. But when it's checked into QA, the code breaks with the below error message:</p>
  
  <pre><code>myRecord.UTCStartTime = TimeZoneInfo.ConvertTimeToUtc(myRecord.StartTime, myTimeZone);
  </code></pre>
  
  <blockquote>
    <p>The conversion could not be completed because the supplied DateTime
    did not have the Kind property set correctly.  For example, when the
    Kind property is DateTimeKind.Local, the source time zone must be
    TimeZoneInfo.Local.</p>
  </blockquote>
  
  <p>On my DEV environment, the above code generates the same error as the QA server. I applied the below change to fix the problem:</p>
  
  <pre><code>DateTime utcStart = DateTime.SpecifyKind(myRecord.StartTime, DateTimeKind.Unspecified);
  myRecord.UTCStartTime = TimeZoneInfo.ConvertTimeToUtc(utcStart, myTimeZone);
  </code></pre>
  
  <p>Why does the first code example work on DEV1's environment but break on my DEV environment and on our QA server?</p>
