Midday in Hawaii will occur at a different time than in Moscow precisely because of the rotation of the Earth, so to make sense of time around the world and to calculate what time is it where, time zones were introduced. This happened in the late nineteenth century when a Scottish-Canadian engineer and inventor Sandford Fleming proposed dividing the Earth into 24 slices of 15 degrees each. However, this does not mean that all countries in the GMT time zone have the same hour. That is, a time zone will cover the same countries vertically, which is why the UK and South Africa observe the same time. Once again, this has to do with the rotation of the Earth: noon is noon from North to South, because the poles do not move; West to East, however, sees a difference as the Earth turns around its own axis. Funnily enough, while time zones are technically strictly defined by geography, it can sometimes be a purely political decision. For example, India spans a vast territory with several time zones in the geographical sense, but ever since the colonial era, the country observes only one single time zone from border to border. After all, this is precisely what GMT is: an agreement.

Universal Time UT , a term introduced in , initially represented mean time at Greenwich determined in the traditional way to accord with the originally defined universal day ; from 1 January as decided by the International Astronomical Union in Dublin in , at the initiative of William Markowitz this "raw" form of UT was re-labelled UT0 and effectively superseded by refined forms UT1 UT0 equalised for the effects of polar wandering [16] and UT2 UT1 further equalised for annual seasonal variations in Earth rotation rate.
