Sorry, I forgot about your original email.  You should get credit for
that.  My apologies.

If the time zone border had been there since 1970, we wouldn't have
needed an entry for Pontianak in the tz database; we could have just
asked people in Pontianak to use the Jakarta entry.  The news here was
that Indonesian west Borneo has switched since 1970.  This news is not
in Shanks (1995), nor is it in Gwillim Law's summaries of the IATA
data (those summaries started after the switch).

Here is some confirmation:
<> (look for Palangkaraya)
<> (look for Balikpapan)
Balikpapan is not the same as Bandjarmasin, but it's the closest airport
that I could find.

By the way, I just found out about; my guess is
that it is derived from the IATA data.  It gives only standard times,
but that is better than nothing.  Perhaps I should add it to tz-link
as well; I don't know of any other place that publishes the IATA data
on the web.

I'll change the name in my next proposed patch.  But I should warn you
that when I tried to visit that page, I got a message "The daily
bandwidth limit for this member has been exceeded."  Apparently you're
too popular.
