Kevin,
(1) Handy hint: try '\df' once in the psql utility.
This gives a nice list of functions, their return types, and
brief descriptions of what they accomplish.
(2) The function for which you seek is probably "timemi" which
takes a time as its first argument and a time interval
(like 1 day) as its second argument.
For example, same time yesterday:
select timemi('now'::datetime, '1 day'::timespan);
