Oh, I guess I was misunderstanding you. After reading again, I think
you're saying that the generators should generate strictly increasing or
strictly decreasing datetimes.

Here's the part I was having trouble with ... why the highest date?
But I guess the directionality of the generator determines what gets
passed to the generator? If it's generating backwards in time it
would be given the lowest date?
