title: How to specify EDT (daylight saving time) to Exchange Web Services (XML not managed)?

  <p>in the section "Use Registry Key Names for TimeZoneNames", tells me that when I can create a calendar item in Exchange, I can pass it the name of a timezone. This is sort-of working, but how do I name "Eastern Daylight Time"? </p>
  
  <p>Only 'US Eastern Standard Time' is accepted as valid. In works in that I schedule something for say 14:00, when it displays in my Google calendar I see it is displaying at 15:00 EDT, so it used the EST timezone I passed in. Problem is that it sends out reminder emails with the time displayed in "US Eastern Standard Time". </p>
  
  <pre><code>When: Friday, August 30, 2013 2:00 PM-3:00 PM. US Eastern Standard Time
  ... rest of email ...
  </code></pre>
  
  <p>I don't want that text like that. It should say "US Eastern Daylight Time" or something like that.</p>
  
  <p>The soap request contains XML like:</p>
  
  <pre><code>&lt;t:CalendarItem xmlns="http://schemas.microsoft.com/exchange/services/2006/types"&gt;  
      ...
      &lt;Start&gt;2013-08-30T14:00:00&lt;/Start&gt;     
      &lt;t:MeetingTimeZone TimeZoneName="US Eastern Standard Time"&gt;&lt;/t:MeetingTimeZone&gt;
  &lt;t:CalendarItem&gt;
  </code></pre>
  
  <p>This is Exchange Server 2007, SP1.</p>
  
  <p>Here is an image of what the email looks like, in Gmail. (The times are bit different from my above example, sorry).  The appointment time is correct, but it in the email body it calls it "Eastern Standard Time", which is not right -- it should be "Eastern Daylight Time" or something like that.  (Note that line is part of the email body generated by the Exchange Server, it is not something made up by Gmail.)</p>
