Can someone offer an explaination as to what I'm encountering here..

......................................................................................
This code doesn't work...

class Time
  def <=>(other_time)
    self.strftime("%H%M%S%Y%m%d").to_i <=>
other_time.strftime("%H%M%S%Y%m%d").to_i
  end
end

first = Time.local(2006, 10, 21)
last = Time.local(2006, 10, 27)

time_slots = []
range = first..last
range.step(1.hour) do |day_slot|
  time_slots << day_slot
end

time_slots.sort

......................................................................................

the time_slots array isn't populating properly
......................................................................................

This does

first = Time.local(2006, 10, 21)
last = Time.local(2006, 10, 27)

time_slots = []
range = first..last
range.step(1.hour) do |day_slot|
  time_slots << day_slot
end

class Time
  def <=>(other_time)
    self.strftime("%H%M%S%Y%m%d").to_i <=>
other_time.strftime("%H%M%S%Y%m%d").to_i
  end
end

time_slots.sort
