Hi Steven,
A finite time interval, regardless of its size, does not preclude an infinity of subpoints within the interval.
This is not at odds with my point (unintentional pun). Time is a continuous variable and as such, between any two points in time there are an infinity of time locations. In fact, that many time points that it compares in size with the number of points in the real number line. Hence, the rest of the argument.
