This is not a very useful definition. It has no practical application that I can think of. We can’t even be sure that time IS a continuum; there are physicists who have hypothesized that time is quantized, similarly to matter and energy, meaning that a “moment”, or time quantum, could actually have a finite duration. Such theories are neither proven nor disproven at this time.

That, however, doesn’t help us much either. We must remember that we experience time only as mediated by our consciousness, which in turn is controlled by the electrochemical processes that govern the nervous system. I have read (but I forget where; next time I will take better notes) that neuroscientists have determined that what we experience as continuous time is actually a sequence of discrete states (or, to borrow video terminology, “frames”) that our brains assemble after the fact into the narrative that we consciously experience.

Experiments have been conducted that prove that that narrative is faulty; here I actually can refer you to a radio program that discusses them. Reflex actions that we experience as having been caused by our mental activity actually can be shown to occur before the mental activity that “causes” them.

So how does this apply to “the moment”? All we can say without a comprehensive understanding of neuroscience is that what we experience as the moment is a collection of states of various parts of the nervous system that may or may not occur at the same time. The moment is a construct of our brains; without the brain it disappears. There is no perception without a perceiver.

But is there a “self” that is the perceiver? No. The brain, three pounds of gray flesh, is doing the perceiving. If we go looking for the self within the brain (or, more broadly, the nervous system), it disappears.
