United States Senate reintroduced Sunshine Protection Act, enabling Permanent DST
by Phake Nick 14 Nov '22

14 Nov '22

I don't quite understand the legal text of the bill itself [2], but according to my reading, it seems like the bill will end DST across the entire US by shifting the standard time forward an hour, except in states/territories/area that currently doesn't enact DST, which they can choose to follow the new standard time or old standard time? 1: https://www.rubio.senate.gov/public/index.cfm/2021/3/rubio-colleagues-reint… 2: https://www.rubio.senate.gov/public/_cache/files/d34c77c0-acea-4074-bc57-14…

It's related to a portability problem you reported on MS-Windows in response to which in 2018d I committed a patch that introduced RESERVE_STD_EXT_IDS: https://github.com/eggert/tz/commit/24b45243c5210b4196987fdd06e6c288c358a268 When I recently added the randomish filename code to the development version, I neglected to deal with RESERVE_STD_EXT_IDS. The second attached patch should fix this issue. Please give the two patches a try, as I don't use MS-Windows and can't easily test these patches on that platform. > a test run of zdump -v produced way more output than in the last release, the Linux output seems to have become longer too, but maybe this is still under development. That change is intentional, and was caused by this: https://github.com/eggert/tz/commit/ac07b446a3afaa4cb1ae11a91785a201c91f6351 along with some neighboring commits. Thanks for reporting the problems, and I hope the current development version of tzdb addresses the issues you mentioned.

The correct name of the capital city of Ukraine is Kyiv. Kiev is English language, as every other name in the db, not russian.

Re: [tz] Change Request: Europe/Kiev to Europe/Kyiv
by John Hawkinson 18 Mar '22

I do not think we have handled this well; we have not given Victor Perov a good answer. Indeed, to some extent we've made it a "runaround." We can do better. 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 peopl. Victor Perev: I don't have time for a full write-up right now, but please consult the archives of the tz list (http://mm.icann.org/pipermail/tz/ or perhaps https://www.google.com/search?q=site%3Amm.icann.org%2Fpipermail%2Ftz%2F+kyiv which returns 203 results). 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. But we've thought about it and discussed it a lot. The answers you got don't explain that, and that means we have not done a good a job as we should have. Sorry about that. In particular, I think Brian Inglis's answer was actually incorrect in a way that really matters ("Kiev is the correct English spelling"). There are multiple correct English spellings. It used to be that Kiev was the only one, but Kyiv is gaining popularity more and more.

Although you cannot do so, we can handle them a little bit better. Please see https://docs.github.com/en/github/building-a-strong-community/creating-a-pu… You can create a template that explains to a would-be pull request submitter than pull requests will be closed and the project uses the mailing list for development discussions. ("I understand that the tz project does not use pull requests on github, and that if I enter a pull request here, it will be closed and I will be directed to send email to tz(a)iana.org.") For the particular case of regular, recurring issues, it may be worth while to keep one of #15, #26, and #27 open and mark the others as a duplicate of it, so that it is easier for newcomers to understand that this issue has been carefully considered and is not a simple oversight. https://github.com/eggert/tz/pulls?q=kiev Also, not to pick on Brian (again), but if the project policy is not to use github pull requests, it's not great to respond to pull requests on their substance, because it bifurcates the discussion and makes it seem like we actually do use pull requests ("except when we don't"). So what seems like a helpful thing may not be. -- jhawk(a)alum.mit.edu John Hawkinson

Proposal: Sections for different kinds of backward links
by Stephen Colebourne 17 Nov '21

17 Nov '21

I have taken a stab at splitting the `backward` file into sections. This is based on repeated observations made by multiple people that the file represents different kinds of Link. https://github.com/eggert/tz/pull/33 The sections I'm suggesting are: CROSS-ISO - These link across an ISO-3166 boundary EXCESS - These were added despite the locations having the same timekeeping since 1970 RENAMED - These are simple aliases/renames OBSOLETE - These are the most obsolete form of IDs FIXED - These are alternate names for fixed offsets I don't expect this PR to be merged as is - There will probably need to be some consideration as to the correct split, and as to whether each ID is in the correct section. The approach I've used is commented sections with stable section names. Alternate approaches to this problem are possible. For example, a new file could be created for each section. That seems to be more disruptive than the proposed approach. Note that in order for this change to be useful, the section names need to be considered part of the source file API, and maintained over time. thanks Stephen
