Wisconsin is stated as utc-6 but as far a I calculate it is utc-5. I'm really confused cause my pc is set to utc-6 despite and when i look up utc-5 time it's the same. Piie9 (talk) 23:35, 15 June 2025 (UTC)

 Not done Wisconsin is in the North American Central Time Zone, so standard time is UTC-6. However, Wisconsin observes daylight saving time, so the current time in Wisconsin is UTC-5. It will switch back to UTC-6 when daylight saving time ends.

The table in question shows the standard time offset for the locations in it. Guy Harris (talk) 00:19, 16 June 2025 (UTC)

2026-07-29 edit request - another thing that uses UTC date/time

Google Pixel phones use UTC for photo filenames (i.e. pxl_yyyymmdd_hhmmssttt.jpg). Local time is stored as metadata in the file, but the file NAME uses UTC date/time. More information here: https://www.google.com/search?q=pixel+phone+photo+filename+date Perhaps add under "computer systems" but I don't think this is baked into Android - it's part of the camera system on Pixel phones. — Preceding unsigned comment added by ~2026-42212-77 (talk) 21:40, 29 July 2026 (UTC)

Request: Add a short paragraph to the Conversions section explaining that the UTC offset needs to be determined for the specific date and location, particularly where daylight saving time applies.

Proposed text: “When converting between time zones, the relevant UTC offset must be determined for the date and location in question. This is particularly important for locations that observe daylight saving time, as the offset can change during the year. Time zones can also have offsets of 30 or 45 minutes rather than a whole number of hours. Interactive maps can provide a convenient way to compare the UTC offsets used by different locations; for example, the World Time Zone Map provides a visual reference for comparing time zones around the world.”

Conflict of interest: I am associated with Maps.ie, the site linked in the proposed text. EigseSeamusMagUidhir (talk) 23:46, 22 August 2026 (UTC)

 Not done, as promotional. It also sounds like it was written by a computer. –Deacon Vorbis (carbon • videos) 15:27, 23 August 2026 (UTC)

Request: Move Manitoba into the UTC-5 time zone. The Manitoba provincial government has announced that Manitoba will be staying on permanent DST time, since Manitoba's standard timezone is CST (UTC -6) this will leave them staying in UTC-5 year round.

Here is the official announcement by the government for this change: https://news.gov.mb.ca/news/?archive=&item=75397, and the amendment to The Official Time Amendment Act halting the clock change in November and fixing Manitoba to UTC-5 (or as they called it Manitoba Standard Time). https://web2.gov.mb.ca/bills/43-2/b223e.php, https://web2.gov.mb.ca/bills/42-5/b002e.php, https://web2.gov.mb.ca/laws/statutes/ccsm/o030.php CommunistGoose (talk) 15:03, 17 September 2026 (UTC)

On hold. Thank you for the news and sources, but this change is not yet official. The Official Time Amendment Act was passed and assented in 2023, but it awaits a proclamation to come into force. The other bill that you cited (The Official Time Amendment Act, 2025) would have set the change to 8 March 2026 instead of a proclamation, but this bill was not passed. I plan to update Manitoba in this article after the government issues the proclamation. Heitordp (talk) 23:03, 17 September 2026 (UTC)

Might as well do Nunavik at the same time. That was announced late last year. Nfitz (talk) 03:00, 20 September 2026 (UTC)

The news article about the time change in Nunavik was premature. Paul Eggert and Tim Parenti, who maintain the IANA Time Zone Database, contacted Makivvik, the organization mentioned in the article, and reported that Makivvik still had to do the appropriate process to officially change the time, and that it wasn't certain yet. I plan to change Nunavik here only after this proposal is actually implemented. Heitordp (talk) 03:23, 20 September 2026 (UTC)

Yes, I saw that before I posted this, @Heitordp. And from that discussion, the appropriate process isn't defined anywhere (other than the Quebec legislature, which is obviously irrelevant to the corporation and Nunavik. And from a staffer whose position and authority (if any) aren't mentioned. Text in several articles has already been changed - I'm not sure why we'd change some things but not others for something that is hapenning, and is still reported to be taking place by multiple media. That seems disrespectful to me. I'm not sure why you say it's premature. The information was indeed disseminated, and hasn't been contradicted. The news media has continued to report the same for about a year, as recently as the maps that CBC_News published yesterday. Nfitz (talk) 05:59, 20 September 2026 (UTC)

Perhaps we could wait until after November 1, and then look at stories in news outlets such as Nunatsiaq News to see if they are observing standard or daylight saving time. Of course, we would have to be able to verify the actual time any described events occurred, such as sunrise or a lunar eclipse. Jc3s5h (talk) 15:28, 20 September 2026 (UTC)

Yes, that's a good suggestion @Jc3s5h. There is no rush. And the debate is now starting in Kenora about the odd situation they are in, where they'll be GMT-6, while the rest of the province is GMT-5 to the east of them. And Manitoba is GMT-5 to the east of them. I wouldn't be surprised if they change within the next couple of weeks. Nfitz (talk) 20:40, 20 September 2026 (UTC)

The Quebec legislature is indeed the one that can legally change the time in Nunavik. The maintainers of the IANA TZ Database are the ones who said that the news article was premature based on their periodic contacts with the Makivvik staffer, I'm just repeating their conclusion. The news media hasn't continued to report it for a year, the only news articles about this subject were the one in November 2025 and the recent map by CBC, nothing else in between. The fact that other Wikipedia articles have been changed doesn't mean that they are correct, all those changes were based on that single news article from November 2025. I've seen incorrect or premature news many times on many topics. For example, when the Ukrainian legislature passed a law to abolish DST in 2024, many news articles reported that as certain, and multiple Wikipedia users asked me to immediately change the time of Ukraine in articles and maps, but I insisted on waiting because the president still had to sign the law. Indeed, in the end he didn't sign it so Ukraine kept using DST.

Anyway, the time zones listed here and in the IANA TZ Database reflect actual practice, even if contrary to law, especially in Canada. For example the law of Newfoundland and Labrador specifies UTC-3:30/-2:30 for the whole province, but we list most of Labrador as UTC-4/-3 because that's what people actually use there. So if Quebec doesn't change its time law but people in Nunavik actually keep using UTC-4 in November, we can list that here. But I think we should wait until then to see if that will really happen. Heitordp (talk) 18:57, 20 September 2026 (UTC)

The government in Nunavik doesn't give a flying trump about what Quebec City can legally do or not - see also Schefferville (which is so small that it would be only a pixel on a border line on this map). Legally the same is true with Ukraine changing the time zone Crimea, which I see has been recoloured to represent the actual situation. Single news report? There's been multiple news reports by different agencies, and you've ignored the news report I referenced above from this week, that had no ambiguity. I'd argue that there's more than enough evidence that they changed this previously, as per the notification they provided. So there's no need to wait for the colonial overlords to do something. That said, see my resposne above, and there is no rush this close. But I wouldn't bother with any changes then - more so because of the as-of-yet unresolved Kenora situation. Nfitz (talk) 20:54, 20 September 2026 (UTC)

The change in Ukraine that I mentioned had nothing to do with Crimea. In 2024, the Ukrainian legislature voted to adopt UTC+2 all year in all of Ukraine. Many news articles reported it as if the change were already certain, and Wikipedia users asked to change Ukraine to UTC+2 without DST in articles and maps, but I insisted on waiting because the president still had to sign the bill. Months later, the president declined to sign it so Ukraine kept using UTC+2 with UTC+3 around summer. The situation in areas annexed by Russia is different, they use UTC+3 all year since 2022, and the maps here show the situation in practice regardless of legality.

I agree that Nunavik doesn't need approval from Quebec to change its time. But according to this news article from April 2026, the president of Makivvik said that they were still discussing which time to adopt and had to make an agreement with other Nunavik institutions, so the certainty implied in the earlier article of November 2025 seemed premature.

There were indeed other news articles reporting the time change in Nunavik, but they all seemed to be entirely based on the original article of November 2025, not independent information. I did see the recent article that you cited, which claims that Nunavik already changed its time, but I find that article unreliable because it has several inaccuracies: the maps show Southampton Island in UTC-5/-4 but it uses UTC-5 all year; they show some other islands in UTC-4 all year as if part of Nunavik but they are part of Nunavut in UTC-5/-4; they show the area of Golden, BC in UTC-6 all year but so far it decided to remain in UTC-7; they don't show the unofficial deviations in Ontario and Saskatchewan; and there is no legend for dark purple (UTC-3:30). The text of that article, like many others, also says that the Ontario law of 2020 would end DST only if New York and Quebec also did so, but the actual law has no such requirement, it was just the declared intent of the Ontario government at the time before it would proclaim the law into force.

In addition, Makivvik has not announced the time change in its own website, and recent contacts by the maintainers of the IANA TZ Database have not received a clear answer from Makivvik. If the time change were certain, the Makivvik staffer would simply say so. Anyway, let's wait until November to confirm. Heitordp (talk) 02:45, 22 September 2026 (UTC)

That seems an assumption of the motives and competence of the staffer. And the April information seems superceded by recent articles and winter-time maps from CBC CTV. We have enough secondary sources to make the change - but I stand by my original no rush. Nfitz (talk) 16:59, 22 September 2026 (UTC)
