To get sysdate converted in seconds since 01-JAN-1970 try this:

select (SYSDATE - TO_DATE('01011970000000' , 'ddmmyyyyhh24miss')) * 86400 AS epoch_date
FROM   dual
/

I have dates in the database as "seconds since epoch"..

I need to select items where start_time >= epoch(sysdate - 7);

How do I get the sysdate converting to epoch easily within the sql code?
