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

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.

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)
Sorry, I just noticed I was answering an 8 year old comment from someone who hasn't contributed in 8 years. Uporządnicki (talk) 13:55, 21 July 2022 (UTC)

Time in AfricaEdit

Hello, I am unsure whether or not this is the correct place to ask: I created the above list and on the table it includes the date at which a country in Africa adopted its current time zone. Currently, after roughly two days of researching, I am still missing the DRC (west and east), Malawi and Rwanda. does not have any data for them either, and I have looked through several books on time zone histories (including ones I own), scholarly articles and news and law archives of the respective countries, and I have only comeback empty handed thus far. I would really appreciate and be super thankful if anyone could find them or at least give me some leads. Thanks, LunaEatsTuna (talk) 00:46, 6 September 2021 (UTC)

@LunaEatsTuna: Is or any of the references and external links in tz database useful here? Certes (talk) 17:23, 6 September 2021 (UTC)
@Certes: Thank you so muchhhh!!! The IANA mailing list had reliable sources for the DRC, as well as South Africa, Zambia and Zimbabwe (which I had previously cited with TimeAndDate, which is less reliable). You were very helpful! LunaEatsTuna (talk) 04:10, 10 September 2021 (UTC)

About the construction of Template:Hebrew month and Template:Hijri monthEdit

I have left a comment about the way that Template:Hijri month and Template:Hebrew month constructed at Wikipedia talk:WikiProject Templates#About Template:Hebrew month and Template:Hijri month. If you are interested in the template, please see there. ~Cheers, TenTonParasol 02:10, 17 January 2022 (UTC)

Time in ChineseEdit

FYI, a large number of Chinese time templates are up for deletion, see Wikipedia:Templates for discussion/Log/2022 January 28 -- (talk) 04:47, 30 January 2022 (UTC)

Wikipedia:Articles for deletion/Term (time)Edit

Pursuant to Wikipedia:Articles for deletion/Term (time), I have suggested that the very short articles Term (time) and Time limit could be merged into a single broader and more substantial article about the human phenomenon of setting periods of time for the duration or accomplishment of tasks. I'd like to pitch this idea to this project for a determination of what would be the best title and scope for such a combined article. BD2412 T 02:45, 10 February 2022 (UTC)

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)

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

Edit war on Balance wheelEdit

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 sourcesEdit

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 changesEdit

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)
