Careful!

If you're using Time, you're subtracting SECONDS:
irb(main):001:0> today = Time.now
=> Mon Jan 30 00:11:51 EST 2006
irb(main):002:0> puts( today - 7 )
Mon Jan 30 00:11:44 EST 2006
=> nil

That's why I included the " require 'date' " in my example, and
suggested that you could use DateTime if you needed times.
