The time may be 10 am in Beijing and 2 am in New York. It is set on the same time-Greenwich
Mean Time. This is because in 1884, many nations met to decide how to prevent the confusion (混乱)
made by almost every town having its own time.
Such a time rule was devised (设计) by Sir Sanford Fleming (1827-1915). He was an engineer
who lived in Canada. He held a meeting in 1884 to discuss the time problem. He suggested that there
should be 24 meridians (子午线) dividing the world int0 24 time zones (时区). The zero meridian
would pass through the village of Greenwich near London. The time at Greenwich would be called
Greenwich Mean Time, and at each of the 24 meridian lines, the time would go forward or backwards
by one hour.
Twenty-seven nations agreed to this suggestion, and since then GMT has been the centre of
time-keeping for all nations. Most nations have only one time zone. However, large nations such as
the USA and Australia are divided into several time zones.
