In 1954 D.H. Sadler produced a monograph on the changes in time that had been resolved at the 1952 IAU General Assembly. His writeup is clearer than almost anything else for the next 60 years. It was published in Occasional Notices of the RAS, and it has been hard to find until now. https://www.ucolick.org/~sla/leapsecs/twokindsoftime.html This is one of the series of documents produced starting in 1948 and proceeding through the next 20 years where astronomers explained that two kinds of time would be needed to satisfy all applications.
