Pavel Pereslegin updated IGNITE-21557:
--------------------------------------
Description:
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

Also the following case should be investigated
{code:java}
...
static {
TimeZone.setDefault(TimeZone.getTimeZone("Europe/Volgograd"));
}
...
assertQuery("SELECT timestamp with local time zone '1992-09-26
02:30:00' + interval (25) hours")
.returns(sqlTimestamp("1992-09-27T03:30:00.000")).check();
// Expected: 1992-09-27T00:30:00Z <class java.time.Instant>
// Actual: 1992-09-26T23:30:00Z <class java.time.Instant>
