> The following interval arithmetic works incorrectly
> {code:SQL}
> 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
> {code}
> Looks like the main issue is near StandardConvertletTable#convertPlus
> {code:java}
> switch (rex.getType().getSqlTypeName()) {
> case DATE:
> case TIME:
> case TIMESTAMP:
> // *_WITH_LOCAL_TIME_ZONE types missed
> {code}
> and in DatetimeArithmeticImplementor#implementSafe
> {code:java}
> default:
> final BuiltInMethod method =
> operand0.getType().getSqlTypeName() == SqlTypeName.TIMESTAMP
> ? BuiltInMethod.ADD_MONTHS
> : BuiltInMethod.ADD_MONTHS_INT;
> return Expressions.call(method.method, trop0, trop1);
> {code}
> TBD: Calcite issue
