Re: creating a ! method

One potential way to accomplish this is what I did in my MutableTime class[1]. Create a new class that has an internal Time instance variable and -- when you want to 'round' your time -- replace this instance variable with the new Time instance. Judicious use of #method_missing allows your class to pass off any methods it doesn't understand to the time instance.

Time objects are immutable (like numbers, symbols, etc.), so you
cannot alter them directly.
