We argue that the key underpinning of the current stateof-the real-time practice -the priority artifact -and that of the current state-of-the real-time art -deadline-based timeliness optimality -are entirely inadequate for specifying timeliness objectives, for reasoning about timeliness behavior, and for performing resource management that can dependably satisfy timeliness objectives in many dynamic real-time systems. We argue that time/utility functions and the utility accrual scheduling
