Is it acceptable to store the nanosecond from `split-string`, then to convert it
to a number using the same variable name?
(let* ( (tm (format-time-string "%FT%T.%N%z" nil tzone))
(ns (nth 6 (split-string tm "[^[:digit:]]")))
(ns (string-to-number ns)) ; nanoseconds
(ss (nth 0 (parse-time-string tm))) ; seconds
(mm (nth 1 (parse-time-string tm))) ; minutes
(hh (nth 2 (parse-time-string tm))) ; hours
(lc (make-vector 6 0)) )

Yes. The second `ns` just shadows the first in the rest of the code.
