latest zic mishandles Africa/Cairo past 2038?
by Paul Eggert Jan. 11, 2013

Jan. 11, 2013

When I run the command "make check_public" in the tz distribution, several warnings are generated. I'd like to fix things so that it builds cleanly. Let's start with the first warning: "africa", line 190: warning: no POSIX environment variable for zone Africa/Cairo As I understand it, this warning is saying that zic can't deduce a POSIX-style TZ setting for Africa/Cairo time stamps predicted past 2038. But if you look at the data, there's a straightforward POSIX-style setting for that, namely TZ='EET-2'. My guess is that zic is confused because the most-recent Rule is for 2010. Is my guess correct? Is this a bug in zic.c, which can be fixed?

CST for both DST and standard time in Australia/South?
by kavi＠postpro.net Jan. 7, 2013

Jan. 7, 2013

Please see https://bugs.php.net/bug.php?id=63777 The upshot: Australia/South observes daylight savings time, but the tzdata entry specifies 'CST' as the abbreviation year round. Is this a problem?

"non-standard" timezones
by Shawn Steele Jan. 5, 2013

Jan. 5, 2013

Hoping someone can provide examples or something. Are there cases where people are using their own Timezone data? (I'm thinking like a company or research station or something that doesn't snap to some "normal" tz for some reason) Any examples? For non-standard timezones is there a recommendation for naming conventions? (Eg: etc/mine ?) In several systems it's possible to adjust the Timezone data, and, of course someone could edit and install their own versions of the tzdb data on systems that consume it, but I'm curious if it ever happens in practice? Thanks, Shawn

Non-ASCII chars in southamerica file
by Andy Heninger Dec. 27, 2012

Dec. 27, 2012

In the southamerica data file we have several Latin-1 encoded non-ASCII characters. The other data files are 100% ASCII Here they are: $ grep -nP "[\\x80-\\xff]" * southamerica:384:# There's also a note in only one of the major national papers (La Naci�n) at southamerica:390:# (...) anunci� que el pr�ximo domingo a las 00:00 los puntanos deber�n southamerica:393:# A partir de entonces, San Luis establecer� el huso horario propio de southamerica:395:# 2009, el cambio horario quedar� comprendido entre las 00:00 del tercer southamerica:396:# domingo de marzo y las 24:00 del segundo s�bado de octubre. southamerica:815:# I just send a e-mail to Zulmira Brand�o at I think it's fine to allow non-ASCII in comments, but would strongly request that the files be UTF-8 encoded. Anything else leads to immense confusion over what charset is in use. -- Andy

Fwd: [IANA #636310] how to check a time
by Gemma Conn Nov. 30, 2012

Nov. 30, 2012

Hello, Can you point me in the direction of where I can double check that IANA has the correct time for New Zealand? I am worried that IANA has the wrong time for New Zealand, as Google Calendar which claims to use IANA Time Zone Database, displays the incorrect time for New Zealand. It displays GMT + 12 Auckland but it should be GMT + 13 Auckland, as we are observing Daylight Savings time. Sorry I could not find the right place to check this on your website - can you please check for me or tell me where I can check what time the IANA Time Zone Database has for New Zealand? I will let Google know if the mistake lies with them.

Rerun of proposed localtime.c changes

Now that silly season seems to be over, two reruns. First, changes to localtime.c (both attached and below, with tabs mangled).

Make bug-reporting address more configurable
by Joseph S. Myers Nov. 13, 2012

Nov. 13, 2012

When distributing programs from tzcode as part of a larger software distribution, it can be desirable to redirect user bug reports to the bug-reporting system of that distribution as a whole (with a view to then passing along reports or fixes where it's determined that they don't relate to local modifications or packaging). This patch moves the bug-reporting address from being hardcoded in various strings to being in variables that are more convenient to modify in the packaging process. (Some people may wish to use an email address for bug reports, some a URL to a bug tracker and some a URL for instructions on bug reporting. But making the accompanying text configurable rather than just the address bit, to accommodate those variations better, would make things worse for i18n.) diff --git a/Makefile b/Makefile index 5a17164..cbda727 100644 --- a/Makefile +++ b/Makefile @@ -8,6 +8,9 @@ PACKAGE= tzcode # Version numbers of the code and data distributions.

tzcode2012j and tzdata2012j available
by Paul Eggert Nov. 13, 2012

Nov. 13, 2012

The 2012j release of the tz code and data is available. It reflects the following changes recently circulated on the tz mailing list: Libya moved to CET this weekend, but with DST planned next year. (Thanks to Even Scharning, Steffen Thorsen, and Tim Parenti.) Signatures now have the extension .asc, not .sign, as that's more standard. (Thanks to Phil Pennock.) The output of 'zdump --version', and of 'zic --version', now uses a format that is more typical for --version. (Thanks to Joseph S. Myers.) The output of 'tzselect --help', 'zdump --help', and 'zic --help' now uses tz(a)iana.org rather than the old elsie address. zic -v now complains about abbreviations that are less than 3 or more than 6 characters, as per Posix. Formerly, it checked for abbreviations that were more than 3. 'make public' no longer puts its temporary directory under /tmp, and uses the just-built zic rather than the system zic. Various fixes to documentation and commentary. For this release I did not find the time to carefully review Joseph S. Myers's suggestion about BUGEMAIL in <http://mm.icann.org/pipermail/tz/2012-November/018452.html>. At first glance the suggestion seems like a good one, and I'd like to put it into the next release. Here are links to the release files: http://www.iana.org/time-zones/repository/releases/tzcode2012j.tar.gz http://www.iana.org/time-zones/repository/releases/tzdata2012j.tar.gz ftp://ftp.iana.org/tz/releases/tzcode2012j.tar.gz ftp://ftp.iana.org/tz/releases/tzdata2012j.tar.gz Each release file has a GPG signature, which can be retrieved by appending ".asc" to the above URLs. Copies of these signatures are appended to this message. 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 This release corresponds to commit dec96c09a2e3f735292a49929df29028d26c4f1c in the unofficial github repository at <https://github.com/eggert/tz>.
