I found some information on this webpage. Hope it helps.

I got this from http://www.orafusion.com/art_dt.htm

Date arithmetic and date functions :

Adding / subtracting days to / from dates is as simple as adding numbers. Witness:

--subtract 10 days

SQL> select dt - 10 from date_test;

DT-10

This also works for hours, minutes and seconds:

--subtract 3 hrs from date

SQL> select dt-3/24 from date_test;

DT-3/24
