Why the standard time of India has been decided by the local time at 82.5 E longitude?
India’s longitudinal extent varies from 68o7’E to 97o25’E. It will be cumbersome to have local time based on each longitudinal degree. Thus, to avoid the problems of poor coordination and to maintain uniformity, a standard longitudinal of 82o30’E was taken as a reference to determine the standard time of India.
