-- Trino supports timestamp datatypes at various levels of
-- precision from TIMESTAMP(0) to TIMESTAMP(12). These
-- correspond to precision from seconds to picoseconds.
-- Bare TIMESTAMP is an alias for TIMESTAMP(3).

-- Basic Timestamp
SELECT CAST((TIMESTAMP '2012-10-31 01:00 UTC') AS TIMESTAMP);

-- Timestamp with minimum precision (seconds)
SELECT CAST((TIMESTAMP '2012-10-31 01:00 UTC') AS TIMESTAMP(0));

-- Timestamp with maximum precision (picoseconds)
SELECT CAST((TIMESTAMP '2012-10-31 01:00 UTC') AS TIMESTAMP(12));

-- Timestamp with time zone
SELECT
CAST(
(TIMESTAMP '2001-08-22 03:04:05.321 America/Chicago')
AS TIMESTAMP WITH TIME ZONE
);

-- Timestamp without time zone
SELECT
CAST(
(TIMESTAMP '2001-08-22 03:04:05.321 America/Chicago')
AS TIMESTAMP WITHOUT TIME ZONE
);

-- Timestamp with precision and time zone
SELECT
CAST(

AS TIMESTAMP(6) WITH TIME ZONE
);

-- Timestamp with precision and without time zone
SELECT
