Not much change - you don't need all the "selfs":

class ETA < Time
   # Takes a number of seconds until the event
   def self.relative(seconds)
     at Time.now.to_i + seconds
   end

   # Requires http://gist.github.com/116290
   def to_s
     roughly
   end

   # Gives a full textual representation of the time expected time of 
arrival (Time.rfc2822)
   def eta
     rfc2822
   end

   # Has the eta passed?
   def arrived?
     self < Time.now
   end
end

And you can directly compare Time and ETA objects.

Kind regards

	robert
