Default Does temperature affect clocks?

I know this isn't an answer to your question but I highly recommend

the book "Latitude" by Dava Sobel. It's a great historical account
about the quest for a simple and practical method to determine a
ship's latitude in the 18th century. The primary focus is on clocks
designed by John Harrison to determine latitude at sea. Solving the
temperature problem was part of his solution.


"Longitude", not "Latitude".


Yes. Latitude is easy to determine. You just shoot the sun at high noon, and
its deviation from straight up is your latitude. Unfortunately, longitude
requires exact knowledge of the time of day, and this is why accurate
navigation depended on accurate time keeping.
