 The longitudanalextent is 30 degree.The sun rises in the east and sets in the west.It takes 4min. for the sun to move across 1longitude thus the eastern most point of india would be 2hr ahead of the western most point in accordance with the local time.So to avoid confusion in the airand rail timings,conference etc. a standard time is observed all over the country.the standard meridian of india is 82 degree 30 east....

hope this helps ya lakshya..........
