Gain or loss of time with change of position. Cross- ing the 180th meridian. It has been shown that local noon at any meridian is when the sun is on the upper branch of that meridian, that at all places East of that meridian at that in- stant it is past noon, or time is fast of that of the given merid- ian ; at all places W...est of that meridian it is not yet noon, or time is slow of that of the given meridian. Hence it is evident that if a navigator travels East, carrying a watch regulated to the time of the meridian departed from, and if he desires to set the watch to the time of a meridian to the eastward, he must set it ahead at the rate of 1 hour for 15 change of longitude, or 24 hours for every 360 ; in other words, in going east- ward around the world, or through 360 of longitude meas- ured in an easterly direction, he gains a day in his reckoning of time.
