Hi, I've been rummaging through the archives and online, but it may be quicker just to ask. What are the best sundial references (online or books), especially with regards to dials that read mean solar time? Is there a history of sundials (or similar solar devices) being used for accurate and/or precise timing, especially for scientific purposes? I can think of a thousand-and-one interesting question regarding these devices, but at the moment I'm interested in descriptions of how sun-driven clocks have been used for pragmatic daily purposes throughout history and all over the world. Which is to say the pragmatic use cases and requirements for solar timekeeping. (I live in Arizona, so sunshine is taken for granted ;-)
