In this example, the result of the CAST is the timestamp formed from the source expression value '2008-05-14' and the default time '00:00:00' adjusted to UTC by the current session time zone displacement, INTERVAL '01:00' HOUR TO MINUTE. Thus, the value of the CAST is '2008-05-13 23:00:00' at UTC.

The result value of the CAST at UTC is adjusted to the current session time zone displacement, INTERVAL '01:00' HOUR TO MINUTE, so the result of the SELECT statements is: TIMESTAMP '2008-05-14 00:00:00'.

SET TIME ZONE INTERVAL '01:00' HOUR TO MINUTE;
SELECT CAST(DATE '2008-05-14' AS TIMESTAMP(0));
SELECT CAST(DATE '2008-05-14' AS TIMESTAMP(0) AT LOCAL);
