		//		Example: "T00:15:00" creates 15 minute increments
		//		Must divide visibleIncrement evenly
		clickableIncrement: "T00:15:00",

		// visibleIncrement: String
		//		ISO-8601 string representing the amount by which
		//		every element with a visible time in the time picker increases
		//		Set in non Zulu time, without a time zone
		//		Example: "T01:00:00" creates text in every 1 hour increment
		visibleIncrement: "T01:00:00",

		// visibleRange: String
		//		ISO-8601 string representing the range of this TimePicker
		//		The TimePicker will only display times in this range
		//		Example: "T05:00:00" displays 5 hours of options
		visibleRange: "T05:00:00",

		// value: String
		//		Date to display.
		//		Defaults to current time and date.
		//		Can be a Date object or an ISO-8601 string
		//		If you specify the GMT time zone ("-01:00"),
		//		the time will be converted to the local time in the local time zone.
		//		Otherwise, the time is considered to be in the local time zone.
		//		If you specify the date and isDate is true, the date is used.
		//		Example: if your local time zone is GMT -05:00,
		//		"T10:00:00" becomes "T10:00:00-05:00" (considered to be local time),
		//		"T10:00:00-01:00" becomes "T06:00:00-05:00" (4 hour difference),
		//		"T10:00:00Z" becomes "T05:00:00-05:00" (5 hour difference between Zulu and local time)
		//		"yyyy-mm-ddThh:mm:ss" is the format to set the date and time
		//		Example: "2007-06-01T09:00:00"
