Two issues: - The intended range was 9 characters starting from index 1. Since the second argument to String::substring() is the length, 10 is potentially reading further than the string's length (when only providing one fraction digit), causing an assertion failure crash. - The spec's intention to skip the decimal separator by starting at index 1 is incorrect, no decimal separator is present in the result of parsing TimeZoneUTCOffsetFractionalPart. I filed a spec fix for this, see: https://github.com/tc39/proposal-temporal/pull/1999
