This list is moving to freelists, but I'll assume you knew that.
Actually the base value for the standard Oracle dates is Jan 1, 4712 BC. There is a Julian function that will return the number of days since the base. To return the Julian,
select to_char(sysdate,'J') from dual;
Also, Oracle9i has some new date types and you may find one that works
better for your purposes:

Folks:
>From what I gather, Oracle stores dates as the number of elapsed days since Jan 1, 1968. When I query a column of type 'DATE', it returns me the default format, dd-mon-yy. I know I can use to_char(date_col,'YYYYMMDD') etc... to define many output formats.
What can I do to get the raw internal value of the date? i.e. today is 13172.
Thanks.
