Subject: Can't change the value of self

This code: 

--------------
class Time
  
  # Rounds a time sensibly.
  # Currently just hour is supported (as that's the only one needed)
  def round_to(unit = :hour)
    unless min == 0
      new_hour = hour
      new_hour += 1 if min > 30
      time = Time.local(year, month, day, new_hour)
    end
    time
  end
  
  def round_to!(*args)
    self = round_to *args
  end
  
end
--------------

Throws this error:

Can't change the value of self (SyntaxError)
    self = round_to *args

Why doesn't it work? What can I do instead?

Thanks
