There is a precedent in the Emacs manual -- Appendix E, Antinews: "For
those users who live backwards in time [...]"
:-)
I admit there may not be great practical utility in a negative time
range. But the interval is well-defined so it ought to be computed
correctly. I would say that a wrong answer is worse than no answer
since it may be believed correct at first glance, when it is not.
Anyway, I'm including a patch for 6.09 which seems to fix the problem....
