Rails - Oct 2007 - Proper timestamps in callbacks

Yay, another Task model:

## the model
class Task < ActiveRecord::Base
 
attr_accessible :lots, :of, :stuff, :but, :not, :finished_at, :and, :finished

  before_save do
    @before_save.call if @before_save
  end

  def finish
    self.finished = true
    @before_save = proc { self.finished_at = Time.now }
  end
end

## usage
t = Task.find(some_id)
t.finish
t.save

(same code on pastie: http://pastie.caboo.se/109143)

I''m thinking that going self.finished-at = Time.now directly in the
finish method will cause finished_at to be a bit earlier that
updated_at. I want it to be the same.

Ideas? The method above is working, but it seems a bit overkill.
