The output format for time values is set using the TIME_OUTPUT_FORMAT parameter. The default setting is HH24:MI:SS.

Create and load the table:

CREATE OR REPLACE TABLE vardttm (v VARIANT);

Copy

INSERT INTO vardttm SELECT TO_VARIANT(TO_DATE('2024-02-24'));
INSERT INTO vardttm SELECT TO_VARIANT(TO_TIME('20:57:01.123456789+07:00'));
INSERT INTO vardttm SELECT TO_VARIANT(TO_TIMESTAMP('2023-02-24 12:00:00.456'));
INSERT INTO vardttm SELECT TO_VARIANT(TO_TIMESTAMP_LTZ('2022-02-24 13:00:00.123 +01:00'));
INSERT INTO vardttm SELECT TO_VARIANT(TO_TIMESTAMP_NTZ('2021-02-24 14:00:00.123 +01:00'));
INSERT INTO vardttm SELECT TO_VARIANT(TO_TIMESTAMP_TZ('2020-02-24 15:00:00.123 +01:00'));

Copy

Show the TIME values in the data:

SELECT * FROM vardttm WHERE IS_TIME(v);
