Paul, Doane and Shanks
disagree and in this case Doane's probably correct. Or, to take a modern example, what is the time zone of Pangnirntung, Nunavut, Canada? The province disagrees with the city, so city and commercial offices operate in one time zone and provincial offices operate on another. (How will your database address problems like Pangnirtung's?)
With as much diplomacy as possible. hmmm, Thanks so much for your prompt reply. It is a pleasure to receive knowledgable mail. I'm familiar with Zip's son's work as well as the work of Lois and Astrodienst. I have a copy of the ACS atlas on my machine. I guess I should know more about Shanks, but since Pottenger is the better known of the two, I wasn't aware that it was his work that Pottenger was programming. The atlas actually seems to be the most problematic portion of programming astrological dates and I can see the wisdom of Pottenger getting into it at an early point in time. Still, this is a hobby for me and I'm looking to earn money at it (yet). For now, just seeking my mark. Thanks again Paul, Jamie
