defmodule SmallestTimeInterval do
  @moduledoc """
  Given a list of times in a 24-hour period, return the smallest interval between two times in the list. Hint: you can 
  do this in O(n) time! Assume the list is unsorted. 

  Example: 

  $ smallestTimeInterval(['01:00', '08:15', '11:30', '13:45', '14:10', '20:05'])
  $ '25 minutes'
