The Prime Meridian, located in Greenwich, London, represents the 0° longitude for the world standard time, also known as Greenwich Mean Time (GMT).
Mean solar time on the prime meridian is known as Greenwich Mean Time (GMT).
Universal Time (also called UT1) was previously known as Greenwich Mean Time (GMT). This is the mean solar time at the meridian which passes through the Royal Observatory in Greenwich, London.
longitude mean north and south. lattitude mean east and west. there is also the prime meridian. it follows longitude.
All of China switched to UTC+8 in 1980. UTC+8 is the local mean time at 120 degrees east longitude. Unofficially, the two westernmost Chinese provinces, Tibet and Xinjiang, use UTC+6, which is the local mean time at 90 degrees east longitude.
The standard meridian time for Europe is Greenwich Mean Time (GMT)

0 degrees longitude, also known as the Prime Meridian, the Greenwich Meridian or the International Meridian.This is the line(along with the International Date Line opposite) that divides the earth into Eastern and Western hemispheres. The Prime Meridian is also the middle of the Greenwich Mean Time Zone(GMT).The Prime Meridian runs through the following countries.United Kingdom(specifically Greenwich Observatory)FranceSpainAlgeriaMaliBurkina FasoTogoGhanaAntarctica (Queen Maud Land, claimed by Norway)
It requires that the decimal is converted to the form a*10^b where 1 < a ≤ 10 and b is an integer. The standard form is also known as the scientific form.
Greenwich Mean Time (GMT) is the standard time at the Prime Meridian in Greenwich, London. GMT starts at midnight (00:00) at the Prime Meridian and is used as a reference point for time zones around the world.
AM = "Ante - Meridian"PM = "Post - Meridian""Ante" and "post" mean "before" and "after"."Meridian" is the imaginary line in the sky that runs north/south and passes directly over you.In the morning, the sun moves from the eastern horizon toward the meridian. At Noon, the sun crosses the meridian. In the afternoon, the sun has crossed the meridian and moves away from it toward the west.Morning is the time before the sun crosses the meridian = Ante-Meridian = AM.Afternoon and evening is the time after the sun crosses the meridian = Post-Meridian = PM.
