Here's a followup question, based on playing around with this:
Why do the two ways of doing this (which I've stashed into
MyTime.floor) result in objects of different types?

  class MyTime < Time
    def MyTime.floor

  # Way 1
      t = Time.new
      mt = MyTime.at t - t.sec

  # Way 2
      tt = MyTime.at (tm = Time.new) - tm.sec

      [mt,tt].each do |ti|
        puts "#{ti} is of type #{ti.type}"
      end
    end
  end

  MyTime.floor

  Output:
  Fri Feb 23 10:31:00 EST 2001 is of type MyTime
  Fri Feb 23 10:31:00 EST 2001 is of type Time
