info: |
1. Let calendar be the this value.
2. Perform ? RequireInternalSlot(calendar, [[InitializedTemporalCalendar]]).
3. Assert: calendar.[[Identifier]] is "iso8601".
4. Set one to ? ToTemporalDate(one).
5. Set two to ? ToTemporalDate(two).
6. Set options to ? GetOptionsObject(options).
7. Let largestUnit be ? ToLargestTemporalUnit(options, « "hour", "minute", "second", "millisecond", "microsecond", "nanosecond" », "auto", "day").
8. Let result be ! DifferenceISODate(one.[[ISOYear]], one.[[ISOMonth]], one.[[ISODay]], two.[[ISOYear]], two.[[ISOMonth]], two.[[ISODay]], largestUnit).
9. Return ? CreateTemporalDuration(result.[[Years]], result.[[Months]], result.[[Weeks]], result.[[Days]], 0, 0, 0, 0, 0, 0).
