TIME: MEASUREMENT OF:
Reading edition
Our divisions of time are purely arbitrary, and are all based upon the revolution of our earth upon its axis, which thus constitutes a gigantic clock. All other clocks, watches, etc., are adjusted accordingly. This is really our only way of measuring time; subjective feelings are very illusory, and have to be checked-up by other means. The solar day is the basis of all our calculations—a month, a year, etc., being only so many days in length. Our earth, therefore, is the clock by which we measure the time of the Universe!
