creating a ! method

[Kurt V. Hindenburg]

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

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