推荐答案

有几种方法可以做到这一点:

There are several ways to do this:

SELECT 
    (TIMESTAMP '2014-10-01 00:37:31') AT TIME ZONE 'CST',
    FROM_TZ((TIMESTAMP '2014-10-01 00:37:31'), 'CST'),
    CAST((TIMESTAMP '2014-10-01 00:37:31') AT TIME ZONE 'CST' AS TIMESTAMP) 
FROM DUAL;

这取决于结果是否应包括新的时区.

It depends if the result shall include the new time zone or not.
