In my humble opinion, I think the choice TZ made for India, by selecting Kolkata (formerly Calcutta) as the reference location, was not a good choice.
I can understand your point -- but it is definitely not applicable to tzdb data which is not meant to cover historical data: However, the database is not designed for and does not suffice for applications requiring accurate handling of all past times everywhere, as it would take far too much effort and guesswork to record all details of pre-1970 civil timekeeping. (from theory.html) On the contrary, the tzdb rules for selecting a representative location for a time zone are carefully constructed so as to avoid political or other extraneous implications as far as possible. Past experience shows that this is a very advantageous design. Michael Deckers.
