time.el, world-clock default Calcutta/Kolkata?

["Gijs Hillenius" <gijs@hillenius.net>]

Hello

time.el defines

(defcustom zoneinfo-style-world-list
  '(("America/Los_Angeles" "Seattle")
    ("America/New_York" "New York")
    ("Europe/London" "London")
    ("Europe/Paris" "Paris")
    ("Asia/Calcutta" "Bangalore")
    ("Asia/Tokyo" "Tokyo"))

Which for me has been returning the wrong response for Bangalore. This
is because in Debian (Testing and Unstable versions), tzdata no longer
recognises Calcutta. That was the official name until 2001, it is now
Kolkata, and earlier this year Calcutta was removed from tzdata, 

I can easily fix this by installing Debian's tzdata-legacy.

Alternatively, should time.el be modified to define ("Asia/Calcutta"
"Bangalore")?

Kind greetings

Gijs
