title: Calendar event in MS Graph API can't set timezone Mountain Standard Time
body: <p>I am trying to build a select element and add several timezones in United States.</p>
  <p>Able to find EST, CST, PST timezones in us &amp; canada, but was not able to find MST(Mountain Standard Time, UTC-7).</p>
  <p>Regarding the <a href="https://docs.microsoft.com/en-us/graph/api/resources/datetimetimezone?view=graph-rest-1.0" rel="nofollow noreferrer">official document</a>, it says that the <code>timeZone</code> property can be set to any of the time zones currently supported by Windows.</p>
  <p>If I have a look at the date/time setting on windows 10, I can see the MST timezone option.</p>

  <p>And also if I check <a href="https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/default-time-zones" rel="nofollow noreferrer">this document</a>, it has not MST timezone as well.</p>
  <p>Should I just use <code>Mountain Standard Time</code> although it is not in the documents?</p>
