Question

differenciate between a local and standard time

Answer 1

Standard time means that the same time is used throughout some region—usually, it was either offset from Greenwich Mean Time or was the local mean time of the capital of the region. The difference between local mean time and local apparent time is the equation of time.

Answer 2

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.
