    sec-temporal-balancetime steps 3–14:
      3. Set _microsecond_ to _microsecond_ + floor(_nanosecond_ / 1000).
      4. Set _nanosecond_ to _nanosecond_ modulo 1000.
      5. Set _millisecond_ to _millisecond_ + floor(_microsecond_ / 1000).
      6. Set _microsecond_ to _microsecond_ modulo 1000.
      7. Set _second_ to _second_ + floor(_millisecond_ / 1000).
      8. Set _millisecond_ to _millisecond_ modulo 1000.
      9. Set _minute_ to _minute_ + floor(_second_ / 60).
      10. Set _second_ to _second_ modulo 60.
      11. Set _hour_ to _hour_ + floor(_minute_ / 60).
      12. Set _minute_ to _minute_ modulo 60.
      13. Let _days_ be floor(_hour_ / 24).
      14. Set _hour_ to _hour_ modulo 24.
    sec-temporal-balanceisodatetime step 1:
      1. Let _balancedTime_ be ? BalanceTime(_hour_, _minute_, _second_, _millisecond_, _microsecond_, _nanosecond_).
    sec-temporal-builtintimezonegetplaindatetimefor step 3:
      3. Set _result_ to ? BalanceISODateTime(_result_.[[Year]], _result_.[[Month]], _result_.[[Day]], _result_.[[Hour]], _result_.[[Minute]], _result_.[[Second]], _result_.[[Millisecond]], _result_.[[Microsecond]], _result_.[[Nanosecond]] + _offsetNanoseconds_).

      b. If _item_ has an [[InitializedTemporalZonedDateTime]] internal slot, then

        ii. 1. Set _plainDateTime_ to ? BuiltinTimeZoneGetPlainDateTimeFor(_item_.[[TimeZone]], _instant_, _item_.[[Calendar]]).
