ZERO 0 Longitude
Prime meridian is used to fix the world standard time.
The Eastern Standard Time Zone in North America should be centered around 75° west longitude. The Eastern Standard Time Zone in Australia should be centered around 150° east longitude.
The Pacific Standard Time Zone should be centered around 120° west longitude.
rom east to west they are Atlantic Standard Time (AST), Eastern Standard Time (EST), Central Standard Time (CST), Mountain Standard Time (MST), Pacific Standard Time (PST), Alaskan Standard Time (AKST), Hawaii-Aleutian Standard Time (HST), Samoa standard time (UTC-11) and Chamorro Standard Time (UTC+10).
The Earth is globe shaped, and the Sun can't illuminate the World at the same time. Therefore, the time is different as the World rotates. If the time was the same all over the World, when it was noon in daylight, it would be noon in darkness on the other side of the World. Standard time is maintained by making allowance for this differential using the Prime Meridian (zero longitude).

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.
There are 15 degrees of longitude in each standard time zone

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.

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