Okay but my point was you would say someone has consciousness when they are without any higher brain function and lacking a cortex.
And, someone with their higher cortex but a damaged cerebellum, who is no longer able to track time, would not be conscious, by your definition.
I mean if that's your definition then you are welcome to it.
I don't know of any theories of consciousness that consider the tracking of time to be what counts. 🤷. Because of the two examples I give.
