Does 'now' exist? If so, how long is it?

[UnafraidOne]

If you try to conceptualize dividing a meter stick into smaller and smaller lengths you can never come to a place where you can say "these lengths are as small as is possible". You simply get closer and closer to zero length without ever reaching it. In other words, conceiving of a length with zero length is impossible. It sounds stupid but perhaps the same problem is working against us when we try to define "now". Now is not a length of time. Nor do many nows add up to the passage of time (any more than "lengths" without length add up to a meter). Now is more like a point on the ruler. Not a point we can ever show someone - it has no length. Rather, a point in the sense of having existence only as a mental construct (used as a tool to measure distance between events in time).

If time is discrete, now is an irreducible, indexical monadic property that has a fixed, uniform length of time. If time is continuous, now is an irreducible, indexical monadic property consisting of a single point in time. I think time wouldn't be time unless irreducible, monadic, indexical properties like now existed.
