(as accepted by `ObjectRef:override_day_night_ratio`) that is equivalent to
the given "time of day" value (as returned by `minetest.get_timeofday`).
* `minetest.encode_png(width, height, data, [compression])`: Encode a PNG

* Passing no arguments disables override, defaulting to sunlight based on day-night cycle
* See also `minetest.time_to_day_night_ratio`,
* `get_day_night_ratio()`: returns the ratio or nil if it isn't overridden
