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_travel.rb
    path of file: ./repos/gitlabhq/gems/gitlab-rspec/lib/gitlab/rspec/configurations
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'active_support/all'
require 'active_support/testing/time_helpers'

module Gitlab
  module 
    
        def self.configure!
          RSpec.configure do |config|
            config.include ActiveSupport::Testing::TimeHelpers

            config.around(:example, :freeze_time) do |example|
              freeze_time { example.run }
            end

            config.around(:example, :time_travel_to) do |example|
              date_or_time = example.metadata[:time_travel_to]

              unless date_or_time.respond_to?(:to_time) && date_or_time.to_time.present?
                raise 'The time_travel_to RSpec metadata must have a Date or Time value.'
              end

              travel_to(date_or_time) { example.run }
            end
          end
