If the system time is properly tied to UTC like srfi-19.scm assumes then I think for a leap second 23:59:59 to 00:00:00 will take 2 seconds of real time.

Oh well, these sort of things always depend on the intended usage, which is why I ask about the current theory. I'd certainly like to tighten up the docs though. _______________________________________________ Guile-devel mailing list Guile-devel@gnu.org http://mail.gnu.org/mailman/listinfo/guile-devel
