Subject: Update for Asia/Calcutta timezone

I seek to update the name of the Asia/Calcutta timezone (+0530 UTC).

Why Calcutta was chosen in 1970 when Calcutta was India's most most populated city.

Since then, 

• Calcutta has been renamed Kolkata (2001)
• Mumbai (formerly Bombay) overtook Calcutta as India's most populous city (1991 census)
Note: Time in India is calculated from Mirzapur near the city of Allahabad.

I seek to change the name of the timezone to 
• Asia/Mumbai (based on the most populous city) OR
• Asia/New Delhi (capital of India, second most populated, more centrally located)
