Hi, I am not sure how the timezone city for India is addressed as Kolkatta (formerly known as Calcutta, and listed in timezone as Calcutta), but this has been the case since I started using Linux, and don't know the reason of the city being used. India has only one timezone. I woulid like to suggest to change the city to Delhi (from Calcutta), which is the capital of India, and has been stable since the country's independence in 1947. If your criteria is the most populous city, it would be Mumbai (formerly Bombay). http://en.wikipedia.org/wiki/List_of_most_populous_cities_in_India Delhi being the capital, is also closer to Allahabad (actually Mirzapur), which is the city used for the official meridian, and Delhi is also the site of National Physical Laboratory, which is used for time keeping.
