I understand this reasoning-- it makes perfect sense from a statistical
perspective.  I didn't mean to be argumentative.  I was just hoping
there was a way to make rrdtool "less accurate."  I've just got a
situation where other people are confused by non-integer values in the
graph and keep reporting it as a bug.

At any rate, its looking like the solution to my problem will be to
quantize the time value that I report to rrdtool on the step boundaries
I've set up in the RRA.
