Great answer. And thanks for the patch. I am applying it.
However, I am sure there are more similar problems, so
I am not at all sure that calculating clock sums, or summing
properties that contain times, will work properly with negative
time intervals. I did not pay any attention to this when writing
those functions, and it is likely that similar problems will exist.
