Date functions

Hi all, I'm porting some code from MySQL to postgresql
at the moment and am running into a bit of a problem.
Is there a way to do something like MySQL's to_days(now())
function? I need to have the database respond back with
its time reduced to the number of days since year 0.

Thanks for any help in advance (and please reply back to
me too, since I don't read this mailing list).

-Brian
