This is the sense in which I meant to include time. I did
not mean in the sense of any system time, but of how many
calls you have made to the generator since -set seed-.
By far the easiest way to ensure reproducibility
is to -set seed- immediately before calling up the
generator.
Poor wording on my part, evidently. Sorry about that.
