Scheduler publishes and unpublishes entities on dates specified by the user.

Code

  // publish_on and unpublish_on dates as variables for use in theme templates.

  // This is not guaranteed, for example in commerce_product the entity is in
  // $variables['product_entity']. This could be extracted if there is a need,
  // but for now just skip if the entity is not immediately available.
