BTW, related to seconds->date, but not to the original question. From
seconds->date documentation:

"The value returned by current-seconds or
file-or-directory-modify-seconds is not portable among platforms.
Convert a time in seconds using seconds->date when portability is
needed."

Making this value portable only requires an addition, so why not make
it portable?

and: "For the second field, values of 60 and 61 are for unusual, but
possible for leap-seconds."

AFAIK, there cannot be more than one leap-second in a minute
(actually, more than one in a month), so I believe the correct range
should be 0..60.  (I also believe there's a typo in the quoted
sentence).
