The paragraph immediately after listing 8.5 suggests that the reader may want to try testing "minutes ago" and "seconds ago" as an exercise. That's fine for the former, but the current implementation of getNiceDate() doesn't handle "seconds ago". The implication is that the reader only has to work on the test case, but in fact they need to modify the getNiceDate() implementation as well.
