Christopher Columbus used a sand-glass to measure the time that his ships were at sea. With today’s marine chronometer, a measurement of time in such a precise and accurate way that it's used as a portable time standard and to determine longitude by means of celestial navigation, he would’ve had a more precise inquiry of the time it takes him to sail from one place to another. Along with Christopher Columbus’s use of the sand-glass to keep time while at sea, he also used a nocturnal, which is an tool used in determining the local time based on the positions of stars in the night sky. Digital clocks, computers, and watches are the primary way to tell time in present day sailing. With digital timekeeping methods, Columbus would have known the exact time at which he was sailing and exactly how long he had been sailing. With today’s digital timekeeping tools you can access the time and a stopwatch within a few clicks or
