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.

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.

This map really brings home how awful this projection is for this map’s purpose and how awful most projections really are near the poles. Greenland isn’t that big. I know this map is Plate Carree, not Mercator, but the size issue of an equirectangular projection is really similar when comparing longitude and size for the entire globe from pole to equator. 15 degrees of longitude for a timezone stops making sense that close to the poles. Greenland would mostly fit in the central time zone of the United States for example. Given its sparse population, dividing it up into 3 timezones seems unnecessary.

Yeah exactly. The concept of time zones themselves really starts to break down at those latitudes, and I don’t think it matters what map projection you show it on (though something like Robinson or Winkel-Tripel, with curved time zones, would definitely make things clearer), it’s a fundamental aspect of the way in which light is hitting the Earth’s surface.
France, Spain, Belgium, and the Netherlands are in the wrong time zone because of Nazis https://lemmy.ca/post/2220899
You should make one that shows how much the official time is wrong with respect to the local time.
That would require way more effort than “find picture from elsewhere on the Internet, scale it down to a size my Lemmy instance will let me upload, and then upload it.”
But anyway, you can basically get that from this chart, for the most part. The rightmost edge of each red section is 30 minutes ahead, or the leftmost is 30 minutes behind of where it should be, when those edges are caused by the time zone itself (rather than national or regional boundaries like state lines), growing by an hour per vertical line.
So, the westernmost parts of Spain are about 1 hour 30 ahead, while the easternmost parts of Poland are 30 minutes behind. The westernmost tip of China is about 3 and a half hours ahead.
