Question

Distinguish between local time and standard time.

Answer 1

Aspect	Local Time	Standard Time
Definition	Local time is the time determined by the position of the sun at a particular place, based on its longitude.	Standard time is the uniform time adopted for the whole country or a large region, usually based on the local time of a central meridian.
Determination	It varies from place to place because it depends on the longitude of the place.	It is based on a single meridian, called the standard meridian, for a country or region to maintain uniformity.
Variation across area	Different places in the same country may have different local times.	The same time is followed throughout the country or region regardless of the longitude differences.
Purpose	It is the actual solar time at a place.	It is used to avoid confusion and maintain uniformity in timekeeping.
Example	Islamabad’s local time is calculated by adding 5 hours to GMT as it is at 75°E longitude.	India’s Standard Time (IST) is calculated from the 82.5°E meridian and is 5 hours and 30 minutes ahead of GMT.
