🏷️ Feature Request Type

UI Feature

🔖 Feature description

A timezone that is based off of UTC+00:00 and does not use DST does not exist, and I think it should be added for convenience sake (for those who want to use UTC)

✔️ Solution

Add a custom timezone that is called UTC that is based off of UTC+00:00 and does not have DST.

❓ Alternatives

Using the Africa/Abidjan timezone (should be the equivalent)

📝 Additional Context

I personally prefer over having UTC and then doing my own timezone addition in my head, and do it that way pretty much for other things too (like my website).
I was looking for an option for UTC, but couldn't find one.

There is no advantage to this feature request, right?

I think this should be left as is

feature request is about adding UTC so people who want UTC can easily choose UTC instead of having to go through many hoops to find something that is similar to UTC

Note that having an extra selection for UTC would be worse, given that we have changed the display of messages to include the timezone marker if an embed is present.

Yes but it's not as clear cut as "choose one and it is UTC". Scoresbysund (now known as Ittoqqortoormiit) is not UTC because it has DST (https://time.is/Ittoqqortoormiit) and UTC does not have DST.

Scoresbysund (now known as [Ittoqqortoormiit](https://en.wikipedia.org/wiki/Ittoqqortoormiit)) is not UTC because it has DST (<https://time.is/Ittoqqortoormiit>) and [UTC](https://en.wikipedia.org/wiki/Coordinated_Universal_Time) does not have [DST](https://en.wikipedia.org/wiki/Coordinated_Universal_Time#Daylight_saving_time).

DST is not supported upstream.
Unless we switch to a different library or dayjs supports this one day, this will not be a feature.

I would also like to have a simple UTC option because the server's timezone is UTC (as are all my servers, so all logs are temporally consistent). Uptime Kuma somehow 'auto-detecting' Europe/London resulted it storing all the timestamps incorrectly, making comparison between its timestamps and log files to determine the cause of an issue unnecessarily difficult.
