title: Advance time for Sidekiq dyno on Heroku
body: <p>For testing purposes, I'd like to advance Sidekiq clock on an Heroku dyno so Time.now returns a date in the future.</p>
  <p>I already do that in Rspec with <code>travel_to</code> but I'd like the full dyno process to have another time.</p>
  <p>Is there a way to do that ?</p>
