Rails - Feb 2006 - slicing and dicing timestamps by month, week, day, etc

I''m trying to finish up a comp lab sign-in app in RoR that includes a
db
table logging each visit with a timestamp. I want to be able to loop 
through the visits table and get a weekly or monthly array and print a 
table of the last four weeks listing a count for the number of visits 
each day. I''ve got it working alright but it''s pretty
ugly...overcoded.

Does anyone know of any similar open source code out there I could get 
some ideas from??
