Sorry, the tz database does not contain information about Chennai, Mumbai, etc. 
Although you could derive from it a similar string (which would mention only 
Kolkata), that would require nontrivial programming.

It sounds like you're asking about access to the MS-Windows time zone registry, 
which is not something we deal with on this list. You might try asking in a 
Microsoft-specific forum.
