It does seem easier to calculate things the way you've done. Certainly leap seconds at 23:59:60Z would complicate this. If there's some elegant way of saying something along the lines of "inclusive of the start year except exclusive of its first instant, and exclusive of the end year except inclusive of its first instant", which is what we currently have, then we should at least include that in the docs.
Why not include both ends, such that a transition at the exact instant that separates year N from year N+1 would appear both at the end of the output from "zdump -c N,N+1", and at the beginning of the output from "zdump -c N+1,N+2", but would appear only once in the middle of the output from "zdump -C N,N+2". --apb (Alan Barrett)
