RE: proposed tz changes for Mongolia, Jan Mayen, Chagos, Indonesia, etc.
A few comments on the proposed tz changes ... Check out my free program World Time Explorer: http://www20.Brinkster.com/timezone50/index.htm ---------- From: Paul Eggert[SMTP:eggert@twinsun.com] Sent: Jueves 31 de Mayo de 2001 3:00 To: tz@elsie.nci.nih.gov Subject: proposed tz changes for Mongolia, Jan Mayen, Chagos, Indonesia, etc.
Here are proposed changes to the tz code and data. The most pressing ones are those for Mongolia, Jan Mayen, and Chagos, as the current UTC offsets are incorrect. Also, these changes affect the current time zone abbreviations for Indonesia.
* Jan Mayen observes Oslo time, not -01:00. Also, add commentary about time in Svalbard and Jan Mayen since 1925. (Thanks to Steffen Thorsen for this.) Actually I would have liked to take credit for that, at least the first part, but I don't deny that Steffen is the expert (by birth, I presume) of norwegian issues :-) ...
* Southwest Borneo switched from +08:00 to +07:00 on 1988-01-01. This entails a new zone 'Asia/Pontianak'. (Thanks to Gwillim Law for this.) Funny, I had it all along right under my nose without noticing it. I send a screenshot from my program World Time Explorer which shows the region. And the line down the middle of Borneo from Malaysia actually *is* a time zone border - I just hadn't realized it, since the line towards Malaysia is a country border, not a time zone border. Can anyone confirm that Palangkaray (with population 148,700 latitude -2.19 and longitude 113.82) is also on GMT+7 just like Pontianak, and that Bandjarmasin (with population 534,600 and latitude -3.34, longitude 114.57) is on GMT+8? The screenshot I send is BorneoSouthWest.gif. The map was developed by Manifold, check out http://www.manifold.net/download/freemaps.html.
* Time Zone Converter has moved.
The new name will be World Time Explorer 1.6 further down on page http://www20.brinkster.com/timezone50/index.htm you can find 3 download buttons for this program, which has maps included from which the graphic that I attach to the mail were taken. Note that it's a beta version, mainly because I want to put some more functionality into the program before releasing it officially, but also because the help file is not up-to-date at all. But the existing functions should work. Note that you can take a snapshot of world time from all distinct time zones in Time Calculator. And by the way, you need a Windows computer to use it ...

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).
Can anyone confirm that Palangkaray (with population 148,700 latitude -2.19 and longitude = 113.82) is also on GMT+7 just like Pontianak, and that Bandjarmasin (with population 534,600 and latitude -3.34, longitude 114.57) is on GMT+8?
Here is some confirmation: <http://www.sumatera-inc.com/go_to_invest/about_indonesia.asp#standtime> <http://www.airportcitycodes.com/aaa/ctydef/pcity.html> (look for Palangkaraya) <http://www.airportcitycodes.com/aaa/ctydef/pcity.html> (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 airportcitycodes.com; 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.
