Uigur, uygur, uighur, weiwuer, uyghur? ----------------------------------------------- From: http://www.uyghurinfo.com/media_advisory.html "The Uyghur Information Agency (UIA) would like to advise the international media to adopt the correct Uyghur terms and names when it covers and writes issues related to the Uyghur people and Eastern Turkestan. First of all, we advise all the international media to use the correct spelling of our ethnic name--Uyghur. ... Second of all, we advise the international media to use the correct Chinese designation for Eastern Turkestan--"Xinjiang". ... Its official Chinese name is "Xinjiang Uyghur Autonomous Region" or "XUAR". ..." Advise: don't use just xinjiang, because this means "new territory", nothing more. Use at least xinjiang uyghur.

IERS Message No. 19: IERS Analysis Campaign
by central_bureau＠iers.org Dec. 20, 2001

*************************************************************************** IERS Message No. 19 December 20, 2001 *************************************************************************** IERS Analysis Campaign to align EOPs to ITRF2000 / ICRF Call for Participation Objective: The intention is to create EOP series with highest possible consistency with ITRF2000 / ICRF and to achieve an overall accuracy of 0.1 mas. This will lead to an intermediate solution until a rigorous combination of EOP, ITRF and ICRF is possible. Therefore, we have to analyse and understand the origin of systematic errors due to the reference frame realization. This campaign will be organized in two major steps: 1. Generation of EOP series that are aligned to ITRF2000 / ICRF by the Analysis Center of the individual techniques (Technique Centers) or other interested groups. 2. Analysis of the aligned series by the Combination Research Centers or other interested groups. Generation of EOP series (step 1): In the first step of this campaign, the Technique Centers or other interested groups are asked to produce EOP series using the ITRF2000 / ICRF as reference frame. Solutions with different constraints on ITRF2000 (ICRF) should be generated as follows: - heavily constrained coordinates + velocities - constraining with formal uncertainties - minimal constraints (NNR, ...) - selected set of sites / quasars for constraints The submitted series will be archived and made available to all participating groups for the second step, the analysis. Analysis of EOP series (step 2): The analysis should consist of: - comparisons with official IERS / EOP series - study consistency of the series and make improvements if necessary - recommendations for future realizations of reference frames The first results may be presented at the EGS General Assembly in Nice, France in April 2002. If you are interested in producing and / or analysing such EOP series or contribute to this campaign in another way, please download the call for participation form from http://www.iers.org/iers/about/ac/campaign.pdf or send a request for the form to central_bureau(a)iers.org . Please submit your proposal by January 18, 2002.

Actually, if my understanding is correct, the term "Eastern Turkestan" refers to the historic name of the region, as a country, when it was outside China's rule for brief periods in history. This region returned to Chinese rule in the 19th century during the Qing Dynasty, and called "Xinjiang", Chinese for "New Territory". Nowadays, the whole province is called Xinjiang Uygur Autonomous Region. Reasons that "Eastern Turkestan" came up more often than "southern Xinjiang" include: * Eastern Turkestan = Xinjiang, not just southern Xinjiang (AFAIK). Try a search on Xinjiang vs. Eastern Turkestan, and Xinjiang is far far more common by orders of magnitude. Google says 103000 hits versus 3160. (and 2600 for "east turkestan", 1190 for "southern xinjiang"... Wow, Google has grown! :-) * The term Xinjiang is relatively newer (since 19th century), and most history books written before that period uses the old name. Xinjiang was called Xiyu (the West Region), Huigu, and a few other names in Chinese literature. * There are some vocal separatist movements who want to "Free Eastern Turkestan", not too unlike "Free Tibet"... Indeed, it seems that nowadays only the separatists are calling the modern Xinjiang province as "Eastern Turkestan", to be interpreted as the Eastern Country of the Turks. Needless to say, at least some Chinese would find that offensive. Also, as a Hong-Kong Chinese myself, I had no idea what "Eastern Turkestan" is until I actually looked it up on the Internet. I am sure most Chinese, including the Uygur and Han people, would be scratching their heads wondering what "Eastern Turkestan" is. Besides, it appears that Eastern Turkestan = the whole Xinjiang, not just part of it, so again, it is not appropriate to call that timezone "Eastern Turkestan" when it is just the westmost region surrounding Kashgar that is within that timezone. Therefore, I recommend changing the comment to something more informative west Xinjiang Uygur Autonomous Region (Eastern Turkestan), China That should better suit the needs of both Chinese and non-Chinese. :-) I have also revised other comment entries for China to make them more informative. Seriously, we Chinese are utterly confused when we are asked to choose a timezone during Linux installation. I myself had no idea why the 5 cities were chosen until I finally compared a world timezone map with a China map. :-) In fact, ALL major Chinese Linux distributions have edited zone.tab to add Asia/Beijing and to revise the comments. (Turbolinux Chinese and Red Flag Linux, for instance.) So, this does point to a real usability (not political) problem. Therefore, I have made all 5 comments more verbose. They may be long, but not as long as a few entries for Canada. :-) I have also changed "Macao" to "Macau". Why? :-) 1. Macau is the official name (in both English and Portuguese). See www.macau.gov.mo, for example. 2. On recent trips to Macau, I can no longer find any signs that say "Macao". 3. ISO 3166 says MO = Macau in English; MO = Macao in French. 4. On Google, Macau: 810000 hits; Macao: 311000 hits. A patch is attached in this message. Please verify and apply.

Are these announcements in the Chinese language, or in > the English language? I would guess both. Let me watch CCTV more often. :-) Anyhow, it would actually sound weird if someone says "Xianzai shi Zhongguo shijian xiawu liang dianzhong."

The city's > population is about 3/4 Uighur, so calling it "Kashi" is a bit like > calling the capital of Mongolia "Ulan Bator" (the anglicization of the > Russian name). According to the Xinjiang provincial web site, "Kashi" is short for "Kashige'er", which is the long-form Chinese name for "Kashgar". Anyhow, personally, I think "Kashige'er" and "Kashgar" are close enough, so I am not too worried about it either. :-) Cheers, Anthony -- Anthony Fok Tung-Ling ThizLinux Laboratory <anthony(a)thizlinux.com> http://www.thizlinux.com/ Debian Chinese Project <foka(a)debian.org> http://www.debian.org/intl/zh/ Come visit Our Lady of Victory Camp! http://www.olvc.ab.ca/

My initial confusion comes from this: All China is really under one official time ("Beijing time" in Chinese), why all those different zones? After looking at glibc/libc/timezone/asia, I realized that zone.tab goes far beyond the current time zone. For it, if two regions historically use different times, they are considered in two time zones, even though they don't have any time difference now. This would certainly help if someone tries to ask, say, what time was it in Beijing at 8pm May 12, 1940 in Chongqing?

tzfiles for an embedded system
by Brian Kuschak Dec. 8, 2001

Dec. 8, 2001

Hello, Our embedded system is very tight on space, but we need to provide a good timezone implementation. I would like to use the standard tzfiles, but optimize them for space. My intention is to modify the zic program to strip out all historical rules and only create tzfiles with information for the year 2000 onwards. I would probably include only a subset of the posix_only rules in our system. I've started playing with the code a bit to do this, and wanted to ask: would it be better to filter out the historical rules as they are read from the files, in inrule() and then remove zones which have no associated rules? Or perhaps read all of the rules and zones and then filter those which are actually written into the tzfiles in outzone()? Any comments would be appreciated (via direct email, I'm not on the list). Thanks, Brian

Dec. 6, 2001

*************************************************************************** IERS Message No. 17 December 6, 2001 *************************************************************************** FIRST ANNOUNCEMENT IERS WORKSHOP on the IMPLEMENTATION of the NEW IAU RESOLUTIONS The International Earth Rotation Service (IERS) will organize a workshop devoted to the implementation of the IAU XXIV General Assembly recommendations on reference systems. The workshop will be held at the Paris Observatory, April 18 - 20, 2002. Background During its XXIV General Assembly in August 2000 the IAU agreed to new resolutions. Namely, the new precession-nutation model was adopted, and the new Celestial Intermediate Pole, Celestial and Terrestrial Ephemeris Origins were defined. As a result the whole spectrum of products within the IERS will be affected. The new resolutions should become effective on January 1, 2003. This workshop is organized to establish the changes in IERS products and analyses that will be required in order to comply with the IAU recommendations. It is anticipated that the structure will be in the nature of a workshop with only a few traditional style presentations. For practical implementations and almanac work it is necessary to - develop a clear explanation of the concepts of the new celestial transformation and the relation to the conventional transformation, - explain the use of the precession-nutation model IAU 2000 A / B, - plan the necessary changes in the data services that will be required, - demonstrate software for the actual implementation of the new systems by users. All researchers and specialists working in field of interest are kindly invited to participate actively in the workshop. A follow-up second announcement with a detailed program will be released in the first half of January 2002 to those who return, not later than December 31, 2001, the attached pre-registration form by mail, fax or e-mail to IERS Central Bureau Subject: Workshop 2002 Bundesamt fuer Kartographie und Geodaesie Richard Strauss Allee 11 D-60598 Frankfurt / Main Germany Fax: #49-69-6333-425 e-mail: central_bureau(a)iers.org --------------------------------------------------------------------------- IERS WORKSHOP on the IMPLEMENTATION of the NEW IAU RESOLUTIONS Pre-registration form Name: Address: Phone: Fax: E-mail: [ ] I intend to participate in the workshop.
