The scheme for including leap seconds that I posted yesterday has been
widely---by at least two readers---misunderstood.  It or a functional
equivalent must/should be used when the underlying time measurement is
a TOD-clock [STCKE] value, an atomic-clock reading, or the like.  It
should NOT be used when this measurement is a TIME-macro based one.
Such values already include leap-second corrections.  To make them a
second time would be otiose, and the result so obtained would be
wrong.

Let me also exploit this post to note that glb-seeking and lub-seeking
binary search are much more important than the traditional
match-seeking binary-search schemes that appear---almost always badly
implemented because phobic about ternary comparisons---in programming
textbooks.
