Sql. Fix TIMESTAMP_WITH_LOCAL_TIME_ZONE interval arithmetic.

select TIMESTAMP WITH LOCAL TIME ZONE '2021-01-01 00:00:00' + INTERVAL 1 MONTH
-- result 2021-01-01 00:00:00.001
select TIMESTAMP WITH LOCAL TIME ZONE '2021-01-01 00:00:00' + INTERVAL 1 YEAR
-- result 2021-01-01 00:00:00.012

    switch (rex.getType().getSqlTypeName()) {
    case DATE:
    case TIME:
    case TIMESTAMP:
// *_WITH_LOCAL_TIME_ZONE types missed

        default:
          final BuiltInMethod method =
              operand0.getType().getSqlTypeName() == SqlTypeName.TIMESTAMP
                  ? BuiltInMethod.ADD_MONTHS
                  : BuiltInMethod.ADD_MONTHS_INT;
          return Expressions.call(method.method, trop0, trop1);
