In addition to the book by Dava Sobel there's a good movie. Links on the Ukiah
Observatory web page below.
The related problem that was much harder to solve is the Latitude. For more on
that see: http://www.prc68.com/I/UkiahObs.shtml I live in Ukiah, California,
where one of these observatories is located.
Another Time Nut you might be interested in reading about is Alfred L. Loomis
chronicled in the book Tuxedo Park by Jennet Connant. Discovered and published
data showing the effect of tides on pendulum clocks.
And of course "Lunar/Solar Tides and Pendulum Clocks (part 1)" at:
