Comment(by nickm):
This seems like a research problem. Randomizing the values naÃvely won't
actually keep a clever program from getting a value for Date; it will just
call Date 10 times and take the mean.
Instead, we could quantize Date(), and randomize the cutoffs between the
quanta, so that the value of Date remains the same (say) for 3.3 seconds
minus a value chosen uniformly at random from between .6 and 0. Would
this break programs people need? Probably. Would this defeat cadence
attacks? Who can say; that's the research problem.
