Still a bad idea, for the same reason: Emacs will display times of solar and lunar phenomena that are wrong, but subtly so. The only default value must be nil so that any calculations are trapped. This is a conundrum: Any value that lets the compilation proceed will (necessarily) produce wrong results. Any value that stops the calculation if the latitude/longitude/zone are not set will stop compilation. Silly.
