One standard time zone is approximately 15 degrees of longitude wide. This width is based on the Earth's rotation, which completes one full turn (360 degrees) in about 24 hours, resulting in a change of 15 degrees per hour. However, time zone boundaries can vary due to political and geographical considerations, so they are not always strictly aligned with these 15-degree intervals.
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).
To accurately perform a local mean time calculation, you need to determine the longitude of the location, convert it to time, adjust for the equation of time, and account for any daylight saving time changes. This will give you the correct local mean time for that specific location.
One. Longitude is derived from the Prime Meridian. Values are measured in relation to this Prime Meridian as East or West longitude. If you withdraw this constant, Prime, then values are given in Positive, Zero, and Negative. The distance between degree's of longitude are also not exact from top to bottom. At the equator they are approx. 69 miles wide, as you go toward the poles they become smaller, with an example being at a Latitude of 45 degree's a degree of longitude is approx: 49miles wide. These can also be more specific in Minutes and Seconds. A good reference to obtain a better understanding would be: http://nationalatlas.gov/articles/mapping/a_latlong.html
180° is half of a full rotation, so the answer is half of a day or twelve hours (ignoring the variables that contribute to the equation of time offset).
The average temperature on Earth is approximately 59 degrees Fahrenheit, but this can vary greatly depending on the location and time of year.
There are 15 degrees of longitude in each standard time zone

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).
IST = India Standard Time The longitude bounds is 68 degrees East - 97 degrees East. The latitude bounds is 35 degrees North - 8 degrees North
Lines of longitude are used to divide the Earth into 24 time zones, each approximately 15 degrees wide. The Prime Meridian (0 degrees longitude) serves as the reference point for Coordinated Universal Time (UTC), which is the basis for setting world standard time. Each time zone is determined by the number of hours ahead or behind UTC they are, making it possible to convert local times to a standardized global time.

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.
The Earth is divided into 24 time zones, each approximately 15 degrees of longitude wide. This system creates the basis for standard time zones around the world.
Every 15 degrees of longitude correspond to an hour of time. The sun will rise and set 1 hour earlier or later at 15 degree intervals. Time zones occur approximately every 15 degrees to compensate for this.
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).
None. No one time zone is 360 degrees that would mean the whole world is one huge time zone.
The central meridian for Eastern Standard Time (EST) is 75 degrees west longitude. This meridian serves as the reference point for the time zone, which is 5 hours behind Coordinated Universal Time (UTC-5).
