A map of the world with vertical lines marking the time zones from UTC-12 to UTC+12. It has a legend:

Wrong Time

“Natural time zones” are 15° in longitude. Land in red observes a time other than the zone it lies within. Smaller islands depict their 12 nautical mile territorial sea, for visual effect. In some cases this includes a state’s archipelagic waters.

      That doesn’t exactly explain why they’re still in those time zones 80 years later, despite only having been under Nazi control for less than 6 years.

    So looking at the US map, it looks like a lot of the red zones are because they’ve arbitrarily defined the borders of the time zone. But US time zones are mostly concerned with making sure that the country is roughly evenly spaced across time zones. Really the northeastern part of the country is what’s out of alignment.

    The entire timezone and Gregorian calendar concepts are outdated political tool. We should’ve switched to consistent UTC-only clock and natural World Calendar or Cotsworth calendar

    We ought to get rid of that minus one time zone - nobody’s using it.

    Actually I think I don’t understand the concept. I think some of the guys in the other time zones might be using the minus one but be wrong.

    Damn this is confusing.

      This one here should be pretty high res. I only scaled it down to 4000 px wide. If you’re not seeing that, it may be something funky with your instance’s proxy—check my instance.

      But the original was 9600 wide iirc. If you want that, it cake from signing up to a mailing list that was linked by someone else in my earlier post in this community.

    Wrong title, it should be:

    A Map of the world showing where the local time zone is wrong more than half hours

    An hour is a human concept, we just divided the day to 24 parts, we could use whatever else division. Local time is correct only on the center longitude, which is a line with zero thickness.

    Also it’s clearly visible that France and Spain are in the wrong time zone, and it was changed by the Nazis. Before WW2 France and Spain was in the same zone as Britain. France changed because of the German occupation, and they forgot to change back after the war.

      Correction: Spain time zone was not changed by the Nazis, It was changed by the Fascists. Franco changed it to have the same time as Germany.

      Fun fact: Have you seen videos of dogs begging for food the day after the time change, having to wait an extra hour? Spaniards were the same, and after the time change, they continued eating lunch and dinner according to their biological clock. That’s why Spaniards have lunch and dinner at later hours.

    “wrong”. technically it’s entirely made up. you can write whatever number you want on the scale where the sun hits the zenith as long as all people nearby can agree to it.

      Yeah, methinks a gradient would have been better instead of a solid demarcation

    World: So China, you are one of the largest landmasses on the planet. How many time zones do you want?

    China: No thanks. * sips tea *

      Would be ideal, but it’s going to be impossible to convince the world to do it.

      They won’t even abolish daylight savings.

      I prefer the current way — I can be in another state or another country and I know that 7am is a good time for breakfast, around noon is a good time for lunch, and so forth. (If you don’t change latitude sure, just go outside to figure this out, but it’s complicated if it’s overcast, or the latitude isn’t what you’re used to, or…)

      Time has a number of meanings — UTC is great for machines, local time is (IMHO) a good concept for humans.

        I think local time would work pretty much the same with a single time zone.

        Single time zone: You get to a new place and look up what time is good for breakfast here

        Many time zones: You get to a new place and look up what time zone you’re in.

        Either way you need to look up what the local time is. But with a single time zone, i think the breakfast time and work hours would be a bit better attuned to sunrise/sunset at your location.

        To me, the main difference is more philosophical. I think it’d encourage a more global perspective.

          Problem with a single time zone is working across them. They’re a huge pain in the ass, but it would be even worse without them. Keeping track of who is in what time zone is difficult, but keeping track of everyone’s schedule without using them as a placeholder would be horrible. ‘what time is a good time for breakfast where you are’ and then doing the math anyway just isn’t as convenient as ‘oh, it’s already 5pm where you are’

          That’s an interesting idea, but I disagree to some extent. Although, I really love the idea of having a single unified global time, it would make traveling inconvenient.

          While staying in a different part of the world, you would need to translate local times to your home time. For example, 21:30 may sound like evening to you, but somewhere else that could be midday, morning or anything else. If you look at museum opening hours, it’s not immediately apparent if it opens just after breakfast or just before lunch time. You would need to do these translations several times a day during your stay to understand when things will happen.

          However, time units are an inconsistent mess, and the calendar is a total disaster. If we need another french revolution to fix that, I’m not going to stand in its way.

          Checking the time zone ones (or more like your phone just switching automatically) vs having to remember the offset every time until you’ve gotten used to it. I’d go with the first one every time

          Many time zones: You get to a new place and look up what time zone you’re in.

          Well, sorta — but it’s no effort at all because my timekeeping device (phone) does this automatically.

          For me, the time of day is internalized in a way that I think is hard to switch. Same as how I was raised with imperial units — even though I prefer (and use professionally) metric, the intuition can be a little harder to get. But to each their own of course :)

      Humans generally are awake during daytime hours and sleeping during night time. It makes sense that the time we assign them are fairly consistent.

      Then there’s China just being ridiculous.

    An item on my bucket list has been to create a map with “gradients” (really just 1-minute bands) of what time the high noon is in that location. This map is just a subset of that, coloring red the areas with an over-30-minute offset. I’d make one for January and one for July to account for DST on both hemispheres.

    I’ll probably convert a publicly available timezone shapefile into a Plate Carée (or similar) projection SVG, create a bitmap “gradient” spanning the entire globe and then use it as texture for the SVG shapes, horizontally offset appropriately.
