One minor annoyance when converting from times to dates
is that one ends up with inexact values from date-year, date-month,
etc.:

#,(date 0 18 38 9 20 10 2006 0 CET #f #f)     ; <-- fine

#,(date 0 34.0 39.0 9.0 20.0 10.0 2006.0 0 CET #f #f)  <-- not so fine

The reason for this is that srfi-19.scm uses (current-seconds)
directly. A quick fix would be to replace this by
(inexact->exact (current-seconds)) but this might become
problematic looking at the ChangeLog entry for (current-seconds):

        - library.scm: `current-seconds' returns a flonum, now [Thanks to
