Which problem did John Harrison's marine chronometer solve relating longitudinal calculation at sea in the 18th Century?

💡 Explanation

John Harrison's chronometer addressed determining longitude by accurately keeping Greenwich time, enabling comparison with local solar time calculated via celestial positioning; the offset determines longitude. Therefore precise time determination provided key, rather than altitude, stable oscillation, or magnetic correction, which are separate and unrelated concerns.
