Dilip R. Ahuja and D.P. Sengupta from the National Institute of Advanced Studies, Bangalore, believe India should have one standard time but the IST should be advanced by half an hour to save energy.
Why would two time zones, or more, be undesirable for India?
In our country, different time zones may cause further alienation between the more prosperous west, north and the south, and the less prosperous east. It would also be difficult to implement, create problems for railways and civil aviation and human errors may lead to catastrophic accidents. But above all, another time zone for the east/northeast will not lead to any significant saving of energy, which is why we pleaded for one time zone but asked the Indian Standard Time to be advanced by half an hour. Incidentally, China has a single time zone, advanced by an hour.
How much energy can possibly be saved if IST is extended by half an hour?
