TypeError: can't convert Redis::Future into an exact number

When using ActiveSupport 7.0.1 with resque, a type error is raised:

TypeError: can't convert Redis::Future into an exact number

Start with the reported stack trace at ActiveSupport's time calculations and Resque's data_store.rb server_time, then reproduce the failure using ActiveSupport 7.0.1 and resque 2.2.0. Done means the worker heartbeat no longer raises a TypeError when Redis returns a Redis::Future.
