    sec-temporal.plaintime.prototype.tozoneddatetime step 10:
      10. Let _instant_ be ? BuiltinTimeZoneGetInstantFor(_timeZone_, _temporalDateTime_, *"compatible"*).

      1. Let _possibleInstants_ be ? GetPossibleInstantsFor(_timeZone_, _dateTime_).
    sec-temporal-builtintimezonegetinstantfor step 14:
      14. Assert: _disambiguation_ is *"compatible"* or *"later"*.

      16. Set _possibleInstants_ to ? GetPossibleInstantsFor(_timeZone_, _later_).
