Who created global time?
Sir Sandford Fleming
In 1878, Sir Sandford Fleming (1827? 1915) developed the system of worldwide time zones that we still use today. He proposed that the world be divided into 24 time zones, each spaced 15 (fifteen degrees) of longitude apart (like 24 sections of an orange).
What is the universal standard of time?
Definition of Universal Time
Universal Time is a solar time standard that reflects the average speed of the Earth’s rotation. Using the prime meridian at 0° longitude as a reference point, it shows the actual length of an average solar day on Earth, which is the time from one solar noon to the next.
