This is something new that’s just occurred to me. Typically we are used to thinking of systems as static entities whereby all components are present simultaneously in space time hence the notion of stasis. However, it is possible that system components may occur temporally so that the systems effect is time-based. For this to work it is essentially that at least one of the components has memory to convey some system state across time. But the key idea here is that the system effect emerges though time even though all system components may not be simultaneously present. These can be fiendishly difficult to unravel systems.
