The standard string representation of a date time string is a simplification of the ISO 8601 calendar date extended format (see Date Time String Format section in the ECMAScript specification for more details). For example, "2011-10-10" (date-only form), "2011-10-10T14:48:00" (date-time form), or "2011-10-10T14:48:00.000+09:00" (date-time form with milliseconds and time zone) can be passed and will be parsed. When the time zone offset is absent, date-only forms are interpreted as a UTC time and date-time forms are interpreted as local time.
