Unspecified trailing optional parameters default to 0. year, month, day, hour, minute, second, millisecond, and microsecond attribute values represent a valid Datetime value if true == Date::isValidYearMonthDay(year, month, day), 0 <= hour < 24, 0 <= minute < 60, 0 <= second < 60, 0 <= millisecond < 1000, and 0 <= microsecond < 1000. Additionally, a valid year, month, day with the time portion equal to 24:00:00.000000 also represents a valid Datetime value.
