+/**
+ * $Id$
+ * 
+ * Created: [Apr 6, 2004]
+ *
+ * Defines a DTSTAMP iCalendar component property.
+ * 
+ * <pre>
+ *     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 &quot;VEVENT&quot;, &quot;VTODO&quot;,
+ *        &quot;VJOURNAL&quot; or &quot;VFREEBUSY&quot; 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 &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.
+ *     
+ *        Format Definition: The property is defined by the following notation:
+ *     
+ *          dtstamp    = &quot;DTSTAMP&quot; stmparam &quot;:&quot; date-time CRLF
+ *     
+ *          stmparam   = *(&quot;;&quot; xparam)
+ * </pre>
+ *
