> Currently {{SqlTimestampAddFunction#deduceType}} does not deal with timestamp_ltz type correctly. Return type of {{timestampadd(..., ..., timestamp_ltz)}} will be timestamp but it should be timestamp_ltz.
> Same issue is for precision datetime_plus.
> Also precision is lost.
> A number of queries highlighting the issue
> {code:sql}
> SELECT timestamp '2003-08-02 12:54:01' - INTERVAL '1.123' SECOND(1, 3);
> SELECT time '12:12:12' + INTERVAL '3.456' SECOND(1, 3);
> SELECT timestampadd(SQL_TSI_FRAC_SECOND, 2, timestamp with local time zone '2016-02-24 12:42:25.000');
> {code}
