title: eventTimezone value
body: <p>can anybody help me about what to insert in the eventTimezone value when adding an event to a calendar? this is my code:</p>
  
  <pre><code>    Intent intent = new Intent(Intent.ACTION_INSERT);
      intent.setType("vnd.android.cursor.item/event");
      intent.putExtra("title", eventName);
      intent.putExtra("beginTime", startCal.getTimeInMillis());
      intent.putExtra("endTime", endCal.getTimeInMillis());   
      intent.putExtra("eventTimezone","Hong Kong");
      startActivity(intent);
  </code></pre>
  
  <p>everything else works fine but the eventTimezone doesnt seem to change the option of the timezone to my desired timezone. what value do i need? ive tried "GMT+1" and "(GMT+8:00) Hong Kong" but they are not working.</p>
