there is a place for solar mean time on List of tz database time zones table Edit

There is a site called ( where you can get solar mean time for the tz database table. I thought it will be a great addition to the table so people can see or calculate time difference before standard time existed.

Example of how the table looks like after the figures are inserted.

CC Coordinates TZ Comments UTC offset UTC offset DST Solar mean time Notes
US +611305−1495401 America/Anchorage Alaska (most areas) −09:00 −08:00 -09:59:36h

Well, one problem I see (and it's a detail, I know) is that then the note about Alaska (most areas) becomes problematic. Most of Alaska is one time zone (the Aleutians are another). That zone is based on the solar mean time at a line of longitude way in the eastern part (the panhandle bordering Canada). Every degree west you go, the solar mean time is 4 minutes less. A degree of longitude is about 39 miles at the equator--roughly half that in Alaska. Uporządnicki (talk) 13:48, 21 July 2022 (UTC)Reply[reply]

Which ISO standard does Anywhere on Earth refer to? Edit

In the Anywhere on Earth page, it refers to "The ISO standard only defines the end of an AoE day." Which ISO standard is this? Is it ISO 8601? Can someone clarify? Penyuan (talk) 17:25, 2 March 2022 (UTC)Reply[reply]

It's not ISO 8601. I have no idea what standard it might be. Jc3s5h (talk) 21:22, 2 March 2022 (UTC)Reply[reply]

There is an edit war going on over the introduction to Balance wheel. Would appreciate more outside opinions at Talk:Balance wheel#Recent changes to introduction.

User script to detect unreliable sources Edit

I have (with the help of others) made a small user script to detect and highlight various links to unreliable sources and predatory journals. Some of you may already be familiar with it, given it is currently the 39th most imported script on Wikipedia. The idea is that it takes something like

  • John Smith "Article of things" Accessed 2020-02-14. (John Smith "[ Article of things]" ''''. Accessed 2020-02-14.)

and turns it into something like

It will work on a variety of links, including those from {{cite web}}, {{cite journal}} and {{doi}}.

The script is mostly based on WP:RSPSOURCES, WP:NPPSG and WP:CITEWATCH and a good dose of common sense. I'm always expanding coverage and tweaking the script's logic, so general feedback and suggestions to expand coverage to other unreliable sources are always welcomed.

Do note that this is not a script to be mindlessly used, and several caveats apply. Details and instructions are available at User:Headbomb/unreliable. Questions, comments and requests can be made at User talk:Headbomb/unreliable.

Recent timezone changes Edit

Please can someone review the recent timezone changes by and roll back if appropriate? I can't find any sources for the ending of DST etc. in these places. Certes (talk) 13:24, 21 July 2022 (UTC)Reply[reply]

"5100" listed at Redirects for discussion Edit

  An editor has identified a potential problem with the redirect 5100 and has thus listed it for discussion. This discussion will occur at Wikipedia:Redirects for discussion/Log/2022 August 24#5100 until a consensus is reached, and readers of this page are welcome to contribute to the discussion.

WikiProject Time in country years talk pages Edit

(copying this question over from the village pump): I've been editing country years talk pages (e.g. Talk:1920 in France) and I'd like to know if WikiProject Time is an appropriate WikiProject for such articles. I've seen it randomly on a few talk pages, but are such articles actually well-suited for this project? (note: we already use WikiProject Years) — Nythar (💬-🎃) 17:47, 6 November 2022 (UTC)Reply[reply]

@Nythar: - yes, I'm wondering same thing since there are thousands of these year lists. Some I've seen with WP Time, but mostly not. Also curious about adding History wikiproject? JoeNMLC (talk) 04:41, 13 January 2023 (UTC)Reply[reply]
JoeNMLC: I've seen WikiProject History on quite a few of these talk pages, and because it seems relevant, I added it to other talk pages to keep the format relatively consistent. However, I'm still not quite sure about adding either WikiProjects History or Time. Any suggestions? I was wondering whether this needs consensus or just an agreement between two or three WikiProject members. — Nythar (💬-❄️) 01:04, 14 January 2023 (UTC)Reply[reply]
Nythar: In August 2022, for Template - "Years in Romania", I combined 3 other Romania templates into that one. After that, on some of those years, if a Talk page was missing I created with WP Romania, WP List, WP Years. On talk pages for some years it contained Romania only, so I added the two (List and Years). Just my opinion, but to keep these year lists focused it may be best to do just the 3 Wikiprojects (Country, List, Years). Adding WP Time and WP History I don't know whether these would attract more editors to improve the Year lists. I'm not sure how active WP Time is but I think WP History is active, especially with so many Biography articles. JoeNMLC (talk) 02:46, 14 January 2023 (UTC)Reply[reply]
JoeNMLC, sorry about the late reply. Anyway, I think these three WikiProjects seem fine. I'll use them in the future for such talk pages. Regards, — Nythar (💬-❄️) 19:59, 15 January 2023 (UTC)Reply[reply]

Citing tz database? Edit

Is it appropriate to cite the tz database itself, or more specifically, the comments written in it?

I'm currently working on and off on the article Time in Alaska and have hit a bit of a roadblock. The Metlakatla Indian Community had briefly used their own timezone, but I wasn't able to find any definitive source as to when and how they did so until I checked the comments of the database. This portion of the file for North America explains the situation pretty well, but I'm unsure as to whether or not it's appropriate to cite it. Unfortunately, it's the only clear source I can find on the issue, aside from the scattered Facebook posts from the MIC themselves listed in the comments.

help wanted: "how long is a long time?" essay Edit

Please consider if you might contribute helpfully to wp:HOWLONGISALONGTIME, a Wikipedia essay which has been needed and yet has only just been started. wp:IANAL, but what is time, anyhow? Is your time the same as my time? Sincerely, --Doncram (talk,contribs) 10:53, 24 March 2023 (UTC)Reply[reply]

Project-independent quality assessments Edit

Quality assessments by Wikipedia editors rate articles in terms of completeness, organization, prose quality, sourcing, etc. Most wikiprojects follow the general guidelines at Wikipedia:Content assessment, but some have specialized assessment guidelines. A recent Village pump proposal was approved and has been implemented to add a |class= parameter to {{WikiProject banner shell}}, which can display a general quality assessment for an article, and to let project banner templates "inherit" this assessment.

No action is required if your wikiproject follows the standard assessment approach. Over time, quality assessments will be migrated up to {{WikiProject banner shell}}, and your project banner will automatically "inherit" any changes to the general assessments for the purpose of assigning categories.

However, if your project has decided to "opt out" and follow a non-standard quality assessment approach, all you have to do is modify your wikiproject banner template to pass {{WPBannerMeta}} a new |QUALITY_CRITERIA=custom parameter. If this is done, changes to the general quality assessment will be ignored, and your project-level assessment will be displayed and used to create categories, as at present.
