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.

    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.
