You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: time_stack_item.rb
    path of file: ./repos/timecop/lib/timecop
    
    the code of the file until where you have to start completion: class Timecop
  # A data class for carrying around "time movement" objects.  Makes it easy to keep track of the time
  # movements on a simple stack.
  class TimeStackItem #:nodoc:
