[tz-announce] 2015f release of tz code and data available
by Paul Eggert Aug. 11, 2015

Aug. 11, 2015

The 2015f release of the tz code and data is available. It reflects the following changes, which were either circulated on the tz mailing list or are relatively minor technical or administrative changes: Changes affecting future time stamps North Korea switches to +0830 on 2015-08-15. (Thanks to Steffen Thorsen.) The abbreviation remains "KST". (Thanks to Robert Elz.) Uruguay no longer observes DST. (Thanks to Steffen Thorsen and Pablo Camargo.) Changes affecting past and future time stamps Moldova starts and ends DST at 00:00 UTC, not at 01:00 UTC. (Thanks to Roman Tudos.) Changes affecting data format and code zic's '-y YEARISTYPE' option is no longer documented. The TYPE field of a Rule line should now be '-'; the old values 'even', 'odd', 'uspres', 'nonpres', 'nonuspres' were already undocumented. Although the implementation has not changed, these features do not work in the default installation, they are not used in the data, and they are now considered obsolescent. zic now checks that two rules don't take effect at the same time. (Thanks to Jon Skeet and Arthur David Olson.) Constraints on simultaneity are now documented. The two characters '%z' in a zone format now stand for the UTC offset, e.g., '-07' for seven hours behind UTC and '+0530' for five hours and thirty minutes ahead. This better supports time zone abbreviations conforming to POSIX.1-2001 and later. Changes affecting installed data files Comments for America/Halifax and America/Glace_Bay have been improved. (Thanks to Brian Inglis.) Data entries have been simplified for Atlantic/Canary, Europe/Simferopol, Europe/Sofia, and Europe/Tallinn. This yields slightly smaller installed data files for Europe/Simferopol and Europe/Tallinn. It does not affect timestamps. (Thanks to Howard Hinnant.) Changes affecting code zdump and zic no longer warn about valid time zone abbreviations like '-05'. Some Visual Studio 2013 warnings have been suppressed. (Thanks to Kees Dekker.) 'date' no longer sets the time of day and its -a, -d, -n and -t options have been removed. Long obsolescent, the implementation of these features had porting problems. Builders no longer need to configure HAVE_ADJTIME, HAVE_SETTIMEOFDAY, or HAVE_UTMPX_H. (Thanks to Kees Dekker for pointing out the problem.) Changes affecting documentation The Theory file mentions naming issues earlier, as these seem to be poorly publicized (thanks to Gilmore Davidson for reporting the problem). tz-link.htm mentions Time Zone Database Parser (thanks to Howard Hinnant). Mention that Herbert Samuel introduced the term "Summer Time". Here are links to the release files: ftp://ftp.iana.org/tz/releases/tzcode2015f.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2015f.tar.gz The files are also available via HTTP as follows: http://www.iana.org/time-zones/repository/releases/tzcode2015f.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2015f.tar.gz As usual, links to the latest release files are here: http://www.iana.org/time-zones/repository/tzcode-latest.tar.gz http://www.iana.org/time-zones/repository/tzdata-latest.tar.gz ftp://ftp.iana.org/tz/tzcode-latest.tar.gz ftp://ftp.iana.org/tz/tzdata-latest.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs.

Aug. 8, 2015

According to many news sources, North Korea is going to change to the 8:30 time zone on August 15, one example: http://www.bbc.com/news/world-asia-33815049 This probably needs a new time zone abbreviation, some ideas: PST - Pyongyang Standard Time PYT - Pyongyang Time (based on the translation below, it sounds like this is the name they are going to use themselves) PT - Pyongyang Time (only two letters) NKT - North Korea Time The official, but extremely slow web site does not seem to support deep linking, but this morning its shown on http://www.kcna.kp/ And the raw text is: (평양 8월 7일발 조선중앙통신) 조선에서 조국해방 70돐을 맞으며 표준시간을 제정하기로 결정하였다. 5일 발표된 최고인민회의 상임위원회 정령에는 다음과 같이 지적되였다. 민족재생의 은인이시며 절세의 애국자이신 위대한 김일성동 지께서 항일의 혈전만리를 헤치시여 강도 일제를 때려부시고 조국을 해방하신 8월 15일은 파란많은 민족수난의 력사에 종지부를 찍고 우리 조국과 인민의 운명개척에서 근본적인 전환을 가져온 력사적인 날이다. 간악한 일본제국주의자들은 반만년의 오랜 력사와 문화를 자랑하던 삼천 리강토를 무참히 짓밟고 전대미문의 조선민족말살정책을 일삼으면서 조선의 표준시간까지 빼앗는 천추에 용서 못할 범죄행위를 감행하였다. 피로 얼룩진 일제의 백년죄악을 결산하고 민족의 자주권을 굳건히 수호 하며 위대한 김일성동지와 김정일동지의 불멸의 존함으로 빛나는 백두산대국 의 존엄과 위용을 영원토록 세계만방에 떨쳐나가려는것은 조선군대와 인민의 철석같은 신념이며 의지이다. 조선민주주의인민공화국 최고인민회의 상임위원회는 조국해방 70돐을 맞 으며 조선군대와 인민의 억척불변의 신념과 의지를 반영하여 다음과 같이 결 정한다. 1. 동경 127°30′을 기준으로 하는 시간(현재의 시간보다 30분 늦은 시 간)을 조선민주주의인민공화국 표준시간으로 정하고 평양시간으로 명명한다. 2. 평양시간은 주체104(2015)년 8월 15일부터 적용한다. 3. 조선민주주의인민공화국 내각과 해당 기관들은 이 정령을 집행하기 위한 실무적대책을 세울것이다.(끝) Which Google Translates to: (Pyongyang, August 07, KCNA) Occasion of 70 anniversary of the national liberation in Korea was decided to establish a standard time. 5 Presidium of the Supreme People's Assembly ordinance published days doeyeotda pointed out as follows: Yisimyeo great benefactor, O peoples of the tax of Comrade Kim Il Sung, who played the Patriots had hurt the anti-Japanese to beat the strength of the clot Great assholes who liberated the country on August 15 in Japan put an end to the work eventful history of our country and the fate of peoples suffering pioneered People In a historic day it brought a fundamental shift. Japan wicked imperialists sameu days while the long history and ruthlessly trampling the Samchully Granite was proud of the culture of the Korean nation's first ever policy of extermination banmannyeon were not venturing a criminal offense to forgiveness takes away the sacral standard time line.

North Korea timezone will change the standard time.
by Jongsoo Lee Aug. 7, 2015

Aug. 7, 2015

Hello North Korea's standard time will be GMT+8:30 from Aug. 15 2015. According to the news, North Korea will push back its standard time by 30 minutes to mark the 70th anniversary of liberation from Japan's colonial rule, the country's official news agency said Friday. North Korea's clocks will be moved back a half-hour starting on the upcoming Aug. 15 anniversary, the Korean Central News Agency said. "The time at 127 degrees 30 minutes east longitude or 30 minutes later than the present one shall be fixed as the standard time of the DPRK and called Pyongyang time," the KCNA report said. DPRK is the country's official name, Democratic People's Republic of Korea. Reference link: http://english.yonhapnews.co.kr/search1/2603000000.html?cid=AEN2015080700155 2315 Regards Jongsoo Lee

suggestions for potential code improvements?
by Kees Dekker July 31, 2015

July 31, 2015

Hi, I extracted the v2015e code and like to ask some things: 1. Why do you not always initialize the variables that are now passed to the INITIALIZE macro (see date.c/localtime.c/zic.c/private.h)? It has (almost) no impact on performance and prevents strict compilers to complain about (potentially) non-initialized variables. If you assign zero upon declaration, the INITIALIZE macro can go away. 2. In asctime_r() (asctime.c:72 and later) two arrays are used for week days. These arrays use a size of '3' for a 3-letter weekday. I expect to use an array of '4', because the '\0' character need to fit too, because the wn and mn variables are used in a call to sprintf() (line 106), where sprintf() normally requires to use 0-terminated strings. By using a '4'-sized array, this is automatically achieved. I don't know whether all sprintf() implementations for all operating systems respect the width/size specifier and allow non-0 terminated string. Now a size/width of '3' is specified, which is not needed if the strings are well terminated, or by accident used somewhere else. I really appreciate if you will do something with these suggestions. Regards, Kees

CST timezone that does not account for DST
by Nilesh Parmar July 31, 2015

July 31, 2015

Hello Team, How can we have CST timezone that does not account for DST ? Using the POSIX string, we can create a timezone called CST that is GMT+6 as follows: [root@hp-dl120gen9-01 ~]# TZ=:CST6 date Thu Jul 9 06:50:29 CST 2015 But this is not consitent if tzdata package is update. Also this does take into account DST change? Thanks, Nilesh P.

Time zone identifiers in user interfaces
by Gilmore Davidson July 30, 2015

July 30, 2015

Hi, long time lurker here, finally throwing my voice into the ring. This is a follow-up to the “Time Zone City for China” thread a week ago (starting at http://mm.icann.org/pipermail/tz/2015-July/022480.html <http://mm.icann.org/pipermail/tz/2015-July/022480.html> ). What particularly caught my attention was the discussion about the use of time zone IDs in user interfaces. Paul Eggert: "The string 'Asia/Shanghai' is a tzdata-specific identifier, not intended to be visible to non-experts.” Guy Harris: "Several time zone selectors I've seen are lazily-written crap that either directly display the tzdb name or tweak it slightly by, for example, splitting it into continent and city and displaying them in a more "user-friendly" form.” Guy Harris: “> Looks like this logic is not well understood by the communities. Then we need to do a better job of explaining it to them.” Not to put too fine a point on it… Yes, there needs to be a better job done of explaining that the city names in time zone IDs should not be used in user interfaces. After reading that discussion I went looking through the tzdb files for guidance around the use of IDs in UIs. All I managed to find was this snippet in the Theory file, on line 385: This naming convention is not intended for use by inexperienced users to select TZ values by themselves (though they can of course examine and reuse existing settings). Distributors should provide documentation and/or a simple selection interface that explains the names; see the 'tzselect' program supplied with this distribution for one example. Given that the above snippet is around halfway through the file – and its wording still provides a fair bit of leeway – it’s not exactly enforcing the stronger opinions displayed on this list about how the IDs should be used. For some context, my domain knowledge is restricted to web sites/applications, so I can’t speak to the OS-level discussions in the previous thread. What I do know is how web developers deal with time zones, if they deal with them at all. For the most part, they use a library specific to their language of choice which slightly abstracts the tzdb data. There are two things these libraries have in common: 1. They use tzdb zone identifiers as the primary part of their API. 2. They don’t have any mentions in their documentation that these identifiers are not for public display. This is not me picking on time zone library authors, as I know that some of them are on this mailing list. My main point is that web developers are, for the most part, so abstracted from the tzdb source that the zone IDs are the only interface they know. Therefore the IDs are what they put in their selection UIs. There’s also the not-insignificant matter of localisation of display names (even Moment Timezone, referenced in tz-link.htm, notes in its API documentation: "Because these strings are generally localized, Moment Timezone does not provide any long names for zones.”). Personally, I didn’t know of the existence of CLDR until I started reading this mailing list. So, instead of dismissing zone-IDs-in-a-user-interface as “lazily written crap”, how about we: a) Acknowledge that most web-based UIs for picking time zones are written by developers who genuinely don’t know any better (I count my past self in this category) b) Make an effort to better educate them about recommended uses of the IDs. I am not intending for this to come across as antagonistic or facetious. I just genuinely want the quality of time zone selectors on the web to improve. Cheers, Gil
