title: Does Outlook correctly handle time zones for .ics (ICalendar) files?
body: <p>I have a program that sends calendar appointments out to users. However these users are in many different time zones. When I create the .ics file, I set the time zone to the local time zone, because they are scheduled here. They then get sent out to the users, who are scattered across many time zones.</p>
  
  <p>Will outlook handle this correctly? As in: if I schedule a person for an 8am meeting and I am in Philadelphia, it should come up as 8am meeting for them in any other time zone. </p>
  
  <p>I know that Outlook works with time zones to an extent, but I couldn't find any good documentation on it. </p>
  
  <p><strong>EDIT:</strong>
  I really should have asked something more along the lines of how do you format it to handle this correctly, here is the format I am currently using. But I have little experience with this so I might be doing it wrong:</p>
