In this example, the current session time zone displacement, INTERVAL '09:00' HOUR TO MINUTE, is used to determine the UTC value '2008-05-31 23:30:00' of the literal.

The CAST result is the source expression value '2008-05-31 23:30:00' at UTC with the target time zone displacement, INTERVAL -'08:00' HOUR TO MINUTE.

The result value of the CAST at UTC is adjusted to time zone displacement, INTERVAL -'08:00' HOUR TO MINUTE, and the result of the SELECT statement is: TIMESTAMP '2008-05-31 15:30:00-08:00'.

SET TIME ZONE INTERVAL '09:00' HOUR TO MINUTE;
SELECT CAST(TIMESTAMP '2008-06-01 08:30:00' AS TIMESTAMP(0) 
   WITH TIME ZONE AT -8);
