Answer 1

Pure Ruby (no Rails)

class Numeric
  def minutes; self/1440.0 end
  alias :minute :minutes

  def seconds; self/86400.0 end
  alias :second :seconds
end

Where 1440 is the number of minutes and 86400 is the number of seconds in a day. Based on how Rails does.

Then you can just let the magic happen:

d + 20.minutes + 10.seconds
