Id wager not one you sea pups have ever picked up a sextant have ya? Ever read the American Practical Navigator? Probably couldnt navigate your way out of a wet paper sack.
If you had ever navigated by the stars you would understand why there are 24 timezones how they came to be and why they are lettered. Long before the advent of Google Maps and daylight savings time. Time zones were developed out of necessity in order locate ones longitudinal position. It was the likes of such great seafaring men as ship captain, astromoner and mathematician Nathaniel Bowditch who divided the world into the time zones by which to navigate. Politicians and the military had nothing to do with it.
Nathaniel Bowditch. March 26, 1773 – March 16, 1838
