The answer is always "just a moment ago".

But, are we justified in expecting "sameness" to even be transitive? Look a
white sheet of paper and at one that's imperceptibly darker. They will
presumably trigger the same neurological response. Then switch the pure
white with one that's imperceptibly darker than the darker one, and repeat
until you end up with black. Does this mean a white sheet triggers the same
reponse as a black one, or that they are operationally the "same"?
