What's the difference between CREATED and DTSTAMP in the iCalendar format?
===

In the [iCalendar spec][1] I find the following about [DTSTAMP][2]:

>   This property is different than the "CREATED" and "LAST-MODIFIED"
   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.

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?
