tzselect.ksh fails under ksh, works under bash
by Alan Barrett July 23, 2014

July 23, 2014

If BASH_VERSION is not set, then tzselect.ksh performs a test in which it attmepts to use the select command, to see whether the select command is available: 84: (eval 'set --; select x; do break; done; exit') 2>/dev/null In the case that the shell is not bash, but the select command is available, then the select command reads a line of input. This is confusing for users, who don't even see a prompt. The attached patch fixes this by redirecting input from /dev/null. I also quoted some variables on general principles. --apb (Alan Barrett)

[PATCH 0/5] Further fixes for Russian time zone changes
by Paul Eggert July 22, 2014

July 22, 2014

Here are some more patches to the tz database to cover the proposed time zone changes in Russia. The basic idea is to not do anything drastic like add new zones until the Russian changes are finalized, but in the meantime to assume that the changes will probably happen and to update existing zones accordingly. Much of the work in generating these patches was by Tim Parenti. Thanks! Paul Eggert (1): Update zone.tab for Russia, and remove Asia/Tiksi comment. Tim Parenti (4): Further fixes for the proposed Russian change on 2014-10-26. Prefer MSK/MSD for Volgograd when on Moscow time. Standardize commentary on the coverage of each Russian zone.

Fwd: Proposal to use 1946-01-01 instead of 1970-01-01 as cutoff point
by Tobias Conradi July 20, 2014

July 20, 2014

Retry, this didn't go through 2013-09-06, due to blocking by the time zone mailing list maintainer. ---------- Forwarded message ---------- From: Tobias Conradi <mail.2012(a)tobiasconradi.com> Date: Fri, Sep 6, 2013 at 12:11 PM Subject: Proposal to use 1946-01-01 instead of 1970-01-01 as cutoff point To: "tz(a)iana.org mailing list" <tz(a)iana.org> Proposal to use 1946-01-01 instead of 1970-01-01 as cutoff point. The concept of country in the database is based on ISO 3166 standards. ISO at http://www.iso.org/iso/home/standards/country_codes.htm says: "The country names in ISO 3166 come from United Nations sources." http://www.un.org/en/aboutun/index.shtml says: "The United Nations is an international organization founded in 1945" So 1946 is the first year where on 1 January the UN existed. This new boundary would exclude to reject data improvement requests like http://mm.icann.org/pipermail/tz/2010-January/016007.html Rejection: http://mm.icann.org/pipermail/tz/2010-January/016010.html Apart from allowing easier inclusion of historic data, the new cutoff point might be easier understandable by most users, assuming the UN is more known than Unix. The new cutoff point is located after WW2 end, thus inclusion of war time offset changes is still not mandatory. -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com -- Tobias Conradi Rheinsberger Str. 18 10115 Berlin Germany http://tobiasconradi.com

It just tells us that Paul was doing the right thing, and that both of your messages were inappropriate. The first one, and then this second one as well. Paul would be justified in banning you from the list because of this, and I think he should. You have clearly shown you have poor judgement and poor understanding of list etiquette, and Paul has been patient with you. To be perfectly clear, your forwarding Paul's message is a violation of etiquette and further demonstrates that you should not be sending email to the list. Hopefully you can enforce that yourself, rather than needing to ban you via administrative/technical means. --jhawk(a)mit.edu John Hawkinson > > On Sun, Jul 20, 2014 at 4:12 AM, Paul Eggert <eggert(a)cs.ucla.edu> wrote: > > Tobias Conradi wrote: > >> > >> Paul Eggert controls ids, removes > >> them, repurposes them as he likes. > > > > > > I'm going to ask you again, privately, to stop making personal comments like > > that.

Bug report for the tzcode2014e.tar.gz, patch included.
by John Cochran July 20, 2014

July 20, 2014

Greetings, I was recently working on an open source project seeing about updating some code based upon the 2010c version of your timezone code and bringing the code up to date based upon your 2014e version. In the process of doing this, I noticed some unneeded object files being linked together in order to create the zic program. As specified by your Makefile, zic is comprised of zic.o, localtime.o, asctime.o, scheck.o, and ialloc.o But as it turns out, localtime.o doesn't supply any symbols that zic.o needs. Additionally, the inclusion of asctime.o is there in order to satisfy a linkage requirement for localtime.o. So zic can be built by linking only zic.o, scheck.o, and ialloc.o together. A context diff of the proposed fix is attached. Sincerely, John Cochran -- There are two ways of constructing a software design: One way is to make it so simple that there are obviously no deficiencies and the other way is to make it so complicated that there are no obvious deficiencies. — C.A.R. Hoare

WG Review: Time Zone Data Distribution Service (tzdist)
by The IESG July 18, 2014

July 18, 2014

A new IETF working group has been proposed in the Applications Area. The IESG has not made any determination yet. The following draft charter was submitted, and is provided for informational purposes only. Please send your comments to the IESG mailing list (iesg at ietf.org) by 2014-07-28. Time Zone Data Distribution Service (tzdist) ------------------------------------------------ Current Status: Proposed WG Assigned Area Director: Barry Leiba <barryleiba(a)computer.org> Mailing list Address: tzdist(a)ietf.org To Subscribe: https://www.ietf.org/mailman/listinfo/tzdist Archive: http://www.ietf.org/mail-archive/web/tzdist/ Charter: Time Zone Data Distribution Service (tzdist) ----------------------------------------------------------- A time zone is a region that has a uniform local time for legal, commercial, and social purposes, with some regions using daylight saving time (DST) rules for part of the year. A local time is defined as a standard offset from Coordinated Universal Time (UTC), and a set of DST rules. Time zone data represents the history, current, and future local time rules for these regions, together with an associated time zone identifier. Time zone data is a critical element of computer systems and devices that make use of local time. In particular, it is critical to any calendaring and scheduling system, such as iCalendar (RFC 5545). Daylight saving time rules, which affect local UTC offsets, can change - sometimes at very short notice (just a few days) - as those rules are typically defined by political processes. Currently, there is no efficient, fast way to ensure that time zone data is updated in a timely and reliable manner on devices that need it. Time zone changes are often delivered as operating system updates, and are thus tied to release schedules that can trail the actual time zone changes by a significant period of time. A service is needed that can provide timely, reliable updates. One added benefit of such a service for iCalendar is the ability for calendaring clients and servers to agree on common, standard definitions of time zone data, removing the need to pass time zone data directly "by value" in iCalendar data. By allowing clients and servers to use time zones "by reference" significant network bandwidth and storage savings can be achieved. This working group will: - Define a time zone data distribution protocol that allows for efficient, timely updates of time zone data to be delivered to clients. This protocol must scale to vast numbers of clients, such as the potential "internet of things" devices, as well as to today's desktop computers and servers. - Define an extension to CalDAV (RFC 4791) to allow clients and servers to use time zones "by reference" to improve the efficiency of the overall protocol. The working group will use the following drafts as initial input for its work: draft-douglass-timezone-service-11 draft-daboo-caldav-timezone-ref-01 The working group will work under the following parameters: - The time zone data distribution protocol will initially be targeted at iCalendar-based clients, but should be flexible enough to deliver time zone data in other formats. - The time zone data will be based on the Time Zone Database (http://www.iana.org/time-zones) but must be able to include any source of time zone data. - The time zone data distribution protocol should also offer an API to allow thin clients to easily make use of time zone data by querying for UTC offsets, offloading the sometimes complex work of expanding recurrence rules to the service. This API should be extensible to support other types of time zone operations in the future. - The time zone data distribution protocol will use current security protocols to protect the integrity and confidentiality of the data as it is distributed, and may also address these issues with respect to retrieval of data from its original source (such as the Time Zone Database). Even public time zone data can represent a significant privacy exposure when it is associated with the user or endpoint that is retrieving it. The following are Out of scope for the working group: - Any changes to the Time Zone Database process or infrastructure, as documented in RFC 6557. However, the WG may work with IANA in order to make integrity checking information, such as public keys, readily accessible for protocol use. - The naming process for time zone identifiers. The working group can consider adding a mechanism, such as a "namespace" prefix, to differentiate different time zone sources, but the nature of the time zone identifiers used will be controlled by the sources themselves. - Lookup protocols or APIs to map a location to a time zone. Milestones: TBD

[PATCH] Be a bit more consistent about Metlakatla and Resolute abbr and comments.

* northamerica (America/Metlakatla): Use the more-common "PST" rather than our invented "MeST" for the abbreviation.

Cite the news report in the commentary, and quote some Juneau graffiti. * zone.tab (America/Resolute): Call it Central Time, not Central Standard Time, since it observes DST now.
