No, it makes me profoundly unhappy, but at least it's
a viable solution.

I think providing `current-tai-seconds' is all around a much
simpler solution.  Then we can have

  (define (tai->posix-seconds tai-secs)
    (- tai-secs (binary-search-range vector-of-leap-seconds))

where the first element of vector-of-leap-seconds is -inf.0.
