Subject: Re: infinite Time


Maybe this approach helps:


class TimeInfinity
  include Comparable

  def <=>(o)
    if o.kind_of? Time then
      1
    elsif o.kind_of? TimeInfinity then
      0
    else
      -1
    end
  end

  def to_s() "Infinity"; end
end

class Time
  alias __compare__ <=>

  def <=>(o)
    o.kind_of?( TimeInfinity ) ? (0-(o<=>self)) : __compare__(o)
  end
end


times=[Time.now, TimeInfinity.new, Time.now]

puts times.join ", "
puts times.sort.join ", "
