That's fascinating. Many thanks. It's always good to see the original paper and this seems not to be acknowledged in the BSS Glossary under `Sources'. I didn't copy the expansion for the Equation of Time but I note that the BSS Glossary has reversed the sign used by Spencer. I take the Spencer view myself. > I wonder what Spencer would think if he knew that his research > on air-conditioning of buildings would be helping diallists > 30 years later? It is amazing that the Equation of Time can have any relevance to air-conditioning! Are Australian air-conditioning units fitted with time-clocks that come on up to a quarter of an hour early or late depending on E? Do the guys who install the plant take longitude offset into account too? Hey, you could even have your air-conditioning plant controlled by a sundial on the roof. Perhaps there is a new market for our trade waiting to be exploited! Frank -
