created_on & updated_on - helper to display date only
All, My initial list is rather busy. I would like to shorten the created_on and updated_on fields to just display the date, not the time. Best wold be a simple 12/28/05 type of presentation. I''ve found the format helpers in rdoc. (ie. distance_of_time_in_words_to_now ), but none seem to be what I''m looking for. How do I control the date format of a timestamp field? Thanks
