You can calculate the longitude of a place when time is given using the Greenwich solar time.
We use longitude and latitude when looking at a map to calculate time.
360° ÷ 24 hr = 15°/hr
Take for example: 75°57′8″W, a line of longitude. We all know that lines of longitude measure the time zones. There are 360 degrees of longitude, and there are 24 hours in a day. Therefore, an hour would be 15 degrees longitude (360/24). 75° would be the number of degrees of longitude. If we take 75 and divide it by 15, we get the number of hours that we want, in this case, 5 hours. 57′ would be the number of minutes. 8″ would be the number of seconds. Sometimes, there are even milliseconds. They are the decimals after the number of
Every latitude extends all the way around the Earth, and is unrelated to the time at any place.If you were to consider longitude instead, the difference in solar time between two longitudes is(longitude #1)degrees minus (longitude #2)degrees/15 hours.
Timekeeping is essential for determining longitude because it relies on differences in time to calculate how far east or west a location is from the Prime Meridian. By comparing the local time at a specific location with the time at the Prime Meridian (such as Greenwich Mean Time), sailors and navigators can calculate their longitudinal position. This method helped improve navigation accuracy and reduce the risk of getting lost at sea.
We use longitude and latitude when looking at a map to calculate time.
As all the lines of longitude meet there, it is impossible to calculate time there.

To calculate standard time, subtract the equation of time from the sundial time, then subtract the longitude from the answer you get.

To calculate the change in time for a given scenario, subtract the initial time from the final time. This will give you the difference in time between the two points.
to locate place and for time calculation
local timeThe time of a place when the midday sun is overhead is called local time.It changes from place to place.The place on the same longitude has the same local time.standard time The local time of the standard meridian of a country is called standard time.It remains same for that particular country.the place on the same longitude has the different standard time.The main difference between local time and standard time is, the local time changes from a place to place, but the standard time remains fixed for the particular country. As per local time, the place/location on the same longitude will have the same local time, but as per the standard time the place on the same longitude will have different standard time.
-- Assign 1 hour difference for each 15 degrees of longitude. -- Remember that western clocks always read earlier than eastern clocks. -- Those two simple rules account for the clock time. If you need the date too and the International Dateline is involved, phone the local library for assistance.
