Subject: creating a ! method

Hello,
  I have this code.  It works fine but I would like to use round_to_interval!.  
I could not figure out how to code that.  Any suggestions?

class Time
   def round_to_interval!
      # how?
   end

   def round_to_interval
      self - (self.min % 10) * 60
   end
end

  Regards,
     Kurt
