Defines a DTSTAMP iCalendar component property.

    4.8.7.2 Date/Time Stamp

       Property Name: DTSTAMP

       Purpose: The property indicates the date/time that the instance of
       the iCalendar object was created.

       Value Type: DATE-TIME

       Property Parameters: Non-standard property parameters can be
       specified on this property.

       Conformance: This property MUST be included in the "VEVENT", "VTODO",
       "VJOURNAL" or "VFREEBUSY" calendar components.

       Description: The value MUST be specified in the UTC time format.

       This property is also useful to protocols such as [IMIP] that have
       inherent latency issues with the delivery of content. This property
       will assist in the proper sequencing of messages containing iCalendar
       objects.

       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.

       Format Definition: The property is defined by the following notation:

         dtstamp    = "DTSTAMP" stmparam ":" date-time CRLF

         stmparam   = *(";" xparam)
