Consider time and time zones. Until 1888 most folks only cared about a 1-3 hour accuracy and used sundials outside of church bell range. But what was the pressing need for time accuracy and time zones in the late 1800? It was so we can catch a train. https://www.quora.com/How-did-Time-Zones-come-to-the-US/answer/Brian-Roemmele?ch=2&share=6d595ce0&srid=Pi3 …

Definitely not true in relation to time keeping. Navigation and surveying both relied on accurate and consistent time keeping. Accurate time is required to know precisely where you are. 1300s for clocktowers in most towns 1600s for accurate pendulum clocks 1816s mass production.

Joel, I hear ya. The fundamental reason for that rail roads to be so accurate, to the second in time was to avert rail road crashes. Prior 100s died by mistiming and bad time zone agreements.

Sea Navigation as far back as phoenicia used relatively accurate time so that they didnt get lost and die. I would wager that more people died by getting lost at sea than all train accidents combined. As for trains standard universal time was first applied to rail on dec 1 1847.

Joel, Prior to 12 noon, November 18th, 1883, time was usually determined locally. It was not standized until later point. A functional system with to-the-second accuracy took place in 1888. As for sea navigation to-the-second accuracy of universal time was not nearly as important
