How to get fetchedResultsController to feed my TableView, based on an object that was retrieved from another FRC in a previous view controller?

If Time stamp is an NSSet you could just pass that along to ViewController B and do away with the fetchedResultsController in B.

Or instead of assigning the entity as done in above, pass along the NSManagedObjectID to ViewController B and do a fetch based on that. This would be a better way of doing if you want to use a fetch controller in B.
