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.

  (byte *range);
• void year range fill
  (byte *range);
• int year slot set

• void day range empty
  (byte *range);
• void day range fill
  (byte *range);
• int day slot set
  (byte *range, int min_from, int min_to);
• int day slot clear
