    Title:      Time-slot functions
    Package:    Standard Function Library (SFL)

    Synopsis:   The time-slot functions provide long-running programs with
                a means to 'switch-on' and 'switch-off' depending on the time
                of day, and day of year.  The intention is that the user can
                configure such programs to be active only between certain
                hours, on certain days, etc.  The time-slot functions work
                with 'range' bitmaps for a day (in seconds) and a year (in
                days), and provide functions to set, clear, and test these
                ranges.
