Profile

This is an unconventional clock concept, with a North Pole-centered azimuthal world map that rotates counterclockwise once per day, just like the Earth does around its axis when viewed from the north. This makes it possible to see roughly what time it is everywhere on Earth at once. The clock hand is the central longitude of your time zone.The star map is also shown, in the same projection, as an overlay. The Sun, Moon and planets are also shown, with accurate ecliptic longitudes to within 1 degree max error, but with their ecliptic latitudes ignored – that is, they are snapped to the ecliptic circle for a cleaner look. The star map makes one clockwise rotation once every year, so that the S
