	//		Returns a Date object given a string formatted according to a subset of the ISO-8601 standard.

	//

	//	description:

	//		Accepts a string formatted according to a profile of ISO8601 as defined by

	//		RFC3339 (http://www.ietf.org/rfc/rfc3339.txt), except that partial input is allowed.

	//		Can also process dates as specified by http://www.w3.org/TR/NOTE-datetime

	//		The following combinations are valid:

	// 			* dates only

	//				yyyy

	//				yyyy-MM

	//				yyyy-MM-dd

	// 			* times only, with an optional time zone appended

	//				THH:mm

	//				THH:mm:ss

	//				THH:mm:ss.SSS

	// 			* and "datetimes" which could be any combination of the above

	//		timezones may be specified as Z (for UTC) or +/- followed by a time expression HH:mm

	//		Assumes the local time zone if not specified.  Does not validate.  Improperly formatted

	//		input may return null.  Arguments which are out of bounds will be handled

	// 		by the Date constructor (e.g. January 32nd typically gets resolved to February 1st)

	//

  	//	formattedString:

	//		A string such as 2005-06-30T08:05:00-07:00 or 2005-06-30 or T08:05:00

	//

	//	defaultTime:

	//		Used for defaults for fields omitted in the formattedString.

	//		Uses 1970-01-01T00:00:00.0Z by default.
