If val is unsigned it will still be accepted with your patch, and
actually if the number cast to unsigned is in the area 0-59 the number
was in that area all the time since it returned from sscanf.
So I can't see how what you said would make any sense at all, except
that if this bothers you, you should maybe use strtol(l) for which the
behaviour for such cases is well-defined and can be checked for...
