title: What's the difference between CREATED and DTSTAMP in the iCalendar format?
body: <p>In the <a href="https://www.rfc-editor.org/rfc/rfc2445" rel="nofollow noreferrer">iCalendar spec</a> I find the following about <a href="https://www.rfc-editor.org/rfc/rfc2445#section-4.8.7.2" rel="nofollow noreferrer">DTSTAMP</a>:</p>
  <blockquote>
  <p>This property is different than the &quot;CREATED&quot; and &quot;LAST-MODIFIED&quot;
  properties. These two properties are used to specify when the
  particular calendar data in the calendar store was created and last
  modified. This is different than when the iCalendar object
  representation of the calendar service information was created or
  last modified.</p>
  </blockquote>
  <p>What does that mean? I'm storing events in a database and want to generate an iCal file. I assume CREATED should be set to whenever the event was created, but what should I set DTSTAMP to?</p>
