In Leo Frankowski's Conrad Stargard novels, Conrad introduces a duodecimal system of arithmetic at the suggestion of a merchant, who is accustomed to buying and selling goods in dozens and grosses, rather than tens or hundreds. He then invents an entire system of weights and measures in base twelve, including a clock with twelve hours in a day (rather than twenty-four.) See these also.


Has anybody had the chance to read any of these Sc-Fi books and if so is there anything of interest? I would go along with the idea of a clock with 12 hours per day and would synchronize this with angular measure so that the Earth moves through one angular minute each minute of time. This is part of the system I have developed.
