michael@0	45	* $Id$
michael@0	46	*
michael@0	47	* Created on 26/06/2005
michael@0	48	*
michael@0	49	* Base class for all representations of time values in RFC2445.
michael@0	50	*
michael@0	51	* <pre>
michael@0	52	* 4.3.4 Date
michael@0	53	*
michael@0	54	* Value Name: DATE
michael@0	55	*
michael@0	56	* Purpose: This value type is used to identify values that contain a
michael@0	57	* calendar date.
michael@0	58	*
michael@0	59	* Formal Definition: The value type is defined by the following
michael@0	60	* notation:
michael@0	61	*
michael@0	62	* date = date-value
michael@0	63	*
michael@0	64	* date-value = date-fullyear date-month date-mday
michael@0	65	* date-fullyear = 4DIGIT
michael@0	66	* date-month = 2DIGIT ;01-12
michael@0	67	* date-mday = 2DIGIT ;01-28, 01-29, 01-30, 01-31
michael@0	68	* ;based on month/year
michael@0	69	*
michael@0	70	* Description: If the property permits, multiple "date" values are
michael@0	71	* specified as a COMMA character (US-ASCII decimal 44) separated list
michael@0	72	* of values. The format for the value type is expressed as the [ISO
michael@0	73	* 8601] complete representation, basic format for a calendar date. The
michael@0	74	* textual format specifies a four-digit year, two-digit month, and
michael@0	75	* two-digit day of the month. There are no separator characters between
michael@0	76	* the year, month and day component text.
michael@0	77	*
michael@0	78	* No additional content value encoding (i.e., BACKSLASH character
michael@0	79	* encoding) is defined for this value type.
michael@0	80	*
michael@0	81	* Example: The following represents July 14, 1997:
michael@0	82	*
michael@0	83	* 19970714
michael@0	84	*
michael@0	85	* </pre>
