North East Students' Organisation (NESO) advisor Samujjal Kumar Bhattacharyya said sun rises in the region at least one hour ahead of Delhi and more than half-an-hour than Mumbai and there was genuine ground to create a separate time zone.
"By the time people in the region go for work following the Indian Standard Time, half the day is already gone. A considerable productive time is wasted in the Northeast. Therefore, we demand a separate time zone for the region," he told a press conference here.
The demand for two time zones in India had first come from the North-Eastern states in the mid-90's with the reasoning that the sun rises in the region between 4:30 AM and 5:00 AM - at least one hour ahead of the rest of the country.
Noted film maker Jahnu Barua too has been quite vocal in raising the demand for past several years, saying many nations worldwide follow different time zones within their territory.
India currently follows a time, which is 5-1/2 hours ahead of the international standard, Greenwich Mean Time (GMT).
