1. The equator is defined as an imaginary line drawn on the Earth and spaced equally between the North and South Pole. ... (often “the Equator”) An imaginary great circle around the Earth, equidistant from the two poles, and dividing earth's surface into the northern and southern hemisphere.

2. The prime meridian is the line of 0 longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere.

3. The International Date Line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway round the world from the prime meridian—the zero degrees longitude established in Greenwich, England, in 1852.

4. The time based on the meridian through a specific place, as a city, in contrast to that of the time zone within which the place is located; the time in a specific place as compared to that of another place to the east or west .

5. Standard time is the synchronization of clocks within a geographical area or region to a single time standard, rather than using solar time or a locally chosen meridian (longitude) to establish a local mean time standard.

6.A time zone is a region of the globe that observes a uniform standard time for legal, commercial and social purposes. ... Some higher latitude and temperate zone countries use daylight saving time for part of the year, typically by adjusting local clock time by an hour.
