What is the time difference between US Central time and Greenwich mean time?

Answer 1

GMT is the timezone in London, England. All other time zones are described relative to GMT. For example, New York is GMT - 5 hours. Los Angeles is GMT - 8 hours. Standard time is how we set our clocks when we are NOT observing Daylight Saving Time. Daylight Saving Time reduces the time-difference between your timezone and GMT by 1 hour. For example, When NYC observes DST, the timezone in NYC becomes GMT-4 (instead of the normal GMT-5)

Answer 2

The equator is the zero latitude line that is imaginary and separates the Northern and Southern Hemisphere. This latitude tine is horizontal. The Greenwich meridian or prime meridian is the zero longitude line from the North Pole to the South Pole that is a vertical line. The equator and prime meridian intersect.

Answer 3

The Greenwich meridian is the one that passes through Greenwich. The prime meridian is the one defined to be at 0°. Currently, they are the same, since the Greenwich meridian is used as the prime meridian, but in past other prime meridians were used, and in future still another one could be used.
