Speaking roughly, your local time is 1 hour earlier than UT for every 15° of your
west longitude, or 1 hour later than UT for every 15° of your east longitude.
But nobody would use this rule of thumb to actually determine their local time.
It's much more useful to use this factoid, plus your wristwatch set to UT and a
few astronomical observations, to determine your longitude.
You can calculate the longitude of a place when time is given using the Greenwich solar time.
-- Latitude is not connected with the passage of time. -- The sun crosses 15 degrees of longitude per hour. So if you know your own longitude, somebody else's longitude, and what time it is over at his place, then you can figure out the solar time where you are. Really seems like a lot of effort and hassle, when you could just ask somebody what time it is, or look at your watch.
The local time of any place changes by 4 minutes for every degree of longitude that it moves east or west from the Greenwich Meridian.
The longitude of the Greenwich Royal Observatory is always 0 degrees.
The latitude and longitude of a place are known as its co-ordinates.

to locate place and for time calculation
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.
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.

Yes. Standard time is that defined along a particular longitude. Local time is related to the longitude of the place concerned. 24 hours = 360 degree. Therefore 1 degree = 4 minutes. Cities to the east of the Standard time longitude are ahead and vice versa for Cities to the west.
