check the Puget Sound Oracle Users Group page (http://www.psoug.org/) at
http://www.psoug.org/reference/timestamp.html
And more information on the INTERVAL DAY TO SECOND datatype at
http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/sql_elements001.htm#SQLRF00207
here's an excerpt from the PSOUG page:
CREATE TABLE tint_test (
msg VARCHAR2(25),
start_date TIMESTAMP WITH TIME ZONE,
end_date TIMESTAMP WITH TIME ZONE,
duration_1 INTERVAL DAY(5) TO SECOND,
duration_2 INTERVAL YEAR TO MONTH);
INSERT INTO tint_test
(msg, start_date, end_date)
VALUES
('my plane ride',
timestamp'2004-08-08 17:02:32.212 US/Eastern',
timestamp'2004-08-08 19:10:12.235 US/Pacific');
UPDATE tint_test
SET duration_1 = (end_date - start_date) DAY(5) TO SECOND,
duration_2 = (end_date - start_date) YEAR TO MONTH;
SELECT msg, duration_1, duration_2 FROM tint_test;
SELECT t.*, end_date - start_date FROM tint_test t;
