ActiveJob adapter for TorqueBox 4.0 scheduler (torquebox-scheduling). Seems to work; place into config/initializers/ and specify the adapter in config/application.rb as follows: config.active_job.queue_adapter = :torquebox_scheduler

torquebox_scheduler_adapter.rb

require 'torquebox-scheduling'
module ActiveJob
  module QueueAdapters
    class TorqueboxSchedulerAdapter
      class << self
        def enqueue(job) #:nodoc:
          TorqueBox::Scheduling::Scheduler.schedule(job.hash, in: 35) do
            Base.execute(job.serialize)
          end
        end

        def enqueue_at(job, timestamp) #:nodoc:
          TorqueBox::Scheduling::Scheduler.schedule(job.hash, at: timestamp) do
            Base.execute(job.serialize)
          end
        end
      end
    end
  end
end
