Locations having a higher W longitude are farther west, and therefore "earlier" in standard time. Each 15° of longitude defines 1 hour's time difference, there being 360° of longitude divided by 24 hours.
So the time at the location at 45°W will be 2 hours [(45-15)/15] earlier, or midnight.
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.
When it is noon in London, England (at 0 degrees longitude), it would be 8 PM at a place located 150 degrees west longitude. This is because for every 15 degrees of longitude difference, there is a one-hour time difference.
If it's noon solar time at 90 degrees W longitude, every 15 degrees of longitude represents a one-hour time difference. So, at 72 degrees W longitude, the solar time would be 2 hours behind (2:00 PM).
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 Black Sea coast of Turkey somewhat north of the city of Ankara, Turkey is located at these coordinates.

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.
When it is noon in London, England (at 0 degrees longitude), it would be 8 PM at a place located 150 degrees west longitude. This is because for every 15 degrees of longitude difference, there is a one-hour time difference.
They go according to lines of longitude. For example, if a place is UTC +8, it is located along approximately 120 degrees east longitude, while the international date line is located at approximately 180 degrees longitude.
If it's noon solar time at 90 degrees W longitude, every 15 degrees of longitude represents a one-hour time difference. So, at 72 degrees W longitude, the solar time would be 2 hours behind (2:00 PM).
Akashi is a city located in southern Hygo Prefecture, Japan, on the Inland Sea west of Kobe. Akashi Municipal Planetarium stands on the meridian of 135 degrees east longitude, and is used to determine Japan Standard Time.
time
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.
There are 24 time zones. The Earth is 360 degrees around the circumference. So, for every 15 degrees of longitude there is one time zone.
The Black Sea coast of Turkey somewhat north of the city of Ankara, Turkey is located at these coordinates.
The Earth rotates at the rate of roughly 15 degrees of longitude per hour.
A polar view of the planet is roughly circular, that is, a total 360 degrees. There are about 24 hours in each day. Divide 360 by 24; the answer is 15, so there are 15 degrees of longitude in each time zone.
