[PATCH] Allow complication with tcc
by Arthur Williams Dec. 31, 2021

Dec. 31, 2021

In zic.c, some multi-line strings were surrounded in parenthesis which prevented tcc from parsing it.

Re: [tz] Change Request: Europe/Kiev to Europe/Kyiv
by John Hawkinson Dec. 15, 2021

A bit of necroposting from my August 2020 email (quoted in full below): > We should take the time to write up a good lengthy explanation of > the issues ("boilerplate"), because this a really important issue of > concern to many people in the world and the project has indeed > thought about it pretty carefully. Dismissing the inquiries because > they are repetitive makes it seem like we haven't, and that > unnecessarily upsets [people]. Has anyone done any work on this, or given thought to it? Serhii Trykoza (hopefully cc'd)'s github PR from the last hour (https://github.com/eggert/tz/pull/35, copied far below) raises the issue again. Please note that the tz project does not use github PRs for issue tracking or commit management, so the PR will likely be closed in short order, which is not an indication of merit. Speaking of boilerplates, I want to again suggest that if this is going to continue to be the project policy, there should be a github pull-request template that makes it clear pull requests are not considered appropriate. Also, when you create a pull request on github now, it reports, "Be sure to review the contributing guidelines." with a hyperlink to https://github.com/eggert/tz/blob/228a93f759cd5f2b0cca9e05eeee3d7cdea07ebf/…. It is not until the last paragraph of that file that any mention is made of pull requests ("[p]lease do not create [them]"), and the fact that the it's a plain text file (rather than CONTRIBUTING.md in markdown) makes it feel pretty unfriendly in the github world. Convertinf the file to markdown and making the "please don't use github pull requests" the first thing, rather than the last thing, would help to get the point across.

The tz project is very conservative in its judgment for when the predominant English spelling of a city has changed, and so far the project has judged that Kiev is still preferred. We discussed it when major English newspapers and style guides changed from Kiev to Kyiv last year (prompted by the US presidential impeachment, which lead to a lot of discussion about Kyiv in America), and we will probably continue to discuss it as time goes on.

[PROPOSED] Fix Y2242 bug in tzdb tarball generation
by Paul Eggert Dec. 13, 2021

Dec. 13, 2021

Use pax format so that ‘make tarballs’ will still work after the year 2242. Without this patch, a far-future ‘make tarballs’ would fail for the same reason the following fails now with GNU tar: $ touch -d 2242-03-16T12:56:32Z future $ tar --format=ustar -cf tar future tar: value 8589934592 out of time_t range 0..8589934591 tar: Exiting with failure status due to previous errors This patch doesn’t change the tarball format for today’s releases since we don’t use any features requiring pax format, which means the tarballs stick to the ustar subset of pax. Although this issue was exposed by the recent switch to ustar format, the Y2242 bug has been present since the tzdb project began, due to historical tar format expiring in 2242 and to POSIX and GNU coming up with incompatible extensions to deal with this expiration. * Makefile (GNUTARFLAGS): Switch from --format=ustar to --format=pax --pax-option='delete=atime,delete=ctime'. * NEWS: Update description of tarball format change. --- Makefile | 3 ++- NEWS | 7 +++++-- 2 files changed, 7 insertions(+), 3 deletions(-) diff --git a/Makefile b/Makefile index d30227a..23dcc14 100644 --- a/Makefile +++ b/Makefile @@ -466,7 +466,8 @@ OK_LINE= '^'$(OK_CHAR)'*$$' # Flags to give 'tar' when making a distribution. # Try to use flags appropriate for GNU tar. -GNUTARFLAGS= --format=ustar --numeric-owner --owner=0 --group=0 \ +GNUTARFLAGS= --format=pax --pax-option='delete=atime,delete=ctime' \ + --numeric-owner --owner=0 --group=0 \ --mode=go+u,go-w --sort=name TARFLAGS= `if tar $(GNUTARFLAGS) --version >/dev/null 2>&1; \ then echo $(GNUTARFLAGS); \ diff --git a/NEWS b/NEWS index edb9a1d..1106ef6 100644 --- a/NEWS +++ b/NEWS @@ -26,9 +26,12 @@ Unreleased, experimental changes instead of GNU format.

Israel DST: Proposed Change of Start of DST
by Ephraim Silverberg Dec. 4, 2021

Dec. 4, 2021

The Minister of Interior, Ayelet Shaked, is proposing to change the Time Law so that DST will start in Israel at 2 a.m. on the *Friday *before the *second *Sunday of March. DST starts, according to the current law, at 2 a.m. on the Friday before the *last* Sunday in March. The proposed change has yet to be brought before the Knesset. I will endeavour to update the list if the proposed change receives Knesset approval.
