Epoch

How do I get the current number of milliseconds since 1970-01-01.

I still have no access to oracle.com so I created a new account to answer this question.

Either you use the difference between timestamp ’1970-01-01 00:00:00 +00:00′ and current_timestamp, or you can use java, which is more portable.

YMMV

create function epoch return number as language java name 
  'java.lang.System.currentTimeMillis() return int';
/ 
select epoch from dual;
