/// @assertion String toIso8601String()
/// Returns an ISO-8601 full-precision extended format representation.
/// The format is yyyy-MM-ddTHH:mm:ss.mmmuuuZ for UTC time, and
/// yyyy-MM-ddTHH:mm:ss.mmmuuu (no trailing "Z") for local/non-UTC time, where:
/// yyyy is a, possibly negative, four digit representation of the year,
/// if the year is in the range -9999 to 9999, otherwise it is a signed six digit
/// representation of the year.
/// MM is the month in the range 01 to 12,
/// dd is the day of the month in the range 01 to 31,
/// HH are hours in the range 00 to 23,
/// mm are minutes in the range 00 to 59,
/// ss are seconds in the range 00 to 59 (no leap seconds),
/// mmm are milliseconds in the range 000 to 999, and
/// uuu are microseconds in the range 001 to 999. If microsecond equals 0,
/// then this part is omitted.
/// The resulting string can be parsed back using parse.
