A History
of Time
Nine instruments follow time from a returning shadow to an agreed atomic second.
A clock begins with repetition: a returning shadow, falling water, a swinging weight, an atom changing state. People choose which repetition to trust, then build their days around it. These instruments follow that choice across history -- from local noon and temple bells to navigation, railway timetables, and atomic time. Every clock measures duration, but it also records what its makers needed time to do.
The chronology

A clock carried home-port time across the ocean.
