GMT-6
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.
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).

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.
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 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.
52 degrees north and 0 degrees longitude intersect in the United Kingdom, specifically in the city of Greenwich, London. Greenwich is known as the starting point for measuring time zones and serves as the reference point for the Prime Meridian.
0 degrees longitude
If the chronometer reads 8 AM Pacific Standard Time at solar noon, it indicates that your location is 120 degrees west longitude. This discrepancy in time suggests that you are 2 hours away from the Pacific Time Zone (120 degrees west longitude corresponds to a 2-hour time difference from Pacific Time).
There is no such longitude. The maximum degrees for lines of longitude is 180 east and west only.
Local mean time at 72 degrees west longitude is UTC-4:48.
