Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatoryin Greenwich, London.
Answer: if its 6pm in ontario it is 12 am on the longitude, so over all a diffence of 6 hours
Greenwich Mean Time (GMT) is the time at the Prime Meridian (0 degrees longitude). Each degree of longitude corresponds to a time difference of 4 minutes. At 20 degrees east longitude, the time would be 20 degrees × 4 minutes = 80 minutes ahead of GMT. Therefore, if it is 12 noon at Greenwich, the time at 20 degrees longitude would be 1:20 PM.
The time in Ghana's capital city, Accra, would be 4 pm. This is because Ghana is located at 0 degrees longitude, making it in the same time zone as Greenwich Mean Time (GMT). Jamaica, at 77 degrees west longitude, is 5 hours behind GMT, so when it's 12 noon in Jamaica, it's 5 pm at 0 degrees longitude.
The Prime Meridian is defined as Zero Longitude. Any longitude that you feel is "close" to zero is close to the Prime Meridian.
Geographers call the 0-degree line of longitude the Prime Meridian. This line runs through Greenwich, England and serves as the starting point for measuring longitude.
0 degrees longitude

0 longitude is the prime meridian. 0 latitude is the equator.
The Prime Meridian is found at 0 degrees longitude. Additionally, this is the longitude line that goes through Greenwich, England which marks the base time zone GMT or UTC that other time zones are relative to.
NORTH POLE
The 0 degree longitude is the imaginary line that goes from pole to pole, passing through Greenwich in London, site of the Royal Observatory. The choice of the zero point for longitudes is arbitrary and many major cities were used. Eventually, in 1884, the Greenwich Meridian was accepted as the internationally agreed zero longitude.
0 degree longitude is is called the Prime Meridian.
The point at which the equator (0° latitude) and the prime meridian (0° longitude) intersect has no real significane but it is in the Atlantic Ocean.
