to_days(now())

Hi all.
I've been looking for a good reference for the built
in time functions and have yet to find any.
What I really need is something similar to MySQL's:
select to_days(now());

This returns the number of days since year one from
the current time in the database.
Thanks for any help in advance (please CC me directly
since I don't subscribe to this mailing list).

-Brian
