The ICARUS is the first portable sundial with which you can read Central European Time (CET) and any zone time in the world. In California the ICARUS shows Pacific Daylight Saving Time (PDT), the Summer Time for the US West coast.
12:00 hours is set on the time zone and you read the time off the time zone scale. In London GMT (Greenwich Mean Time) is standard, the shadow falls at 07:29 hours GMT. Big Ben is obviously showing the correct time.
The date is set on the date scale, opposite you can read the sun's position in the zodiac. Once aligned with the sun, the sundial is positioned in a north-south direction and the gnomon points to the polar star. The ICARUS is a solar compass and a navigator for determining your location.
The ICARUS is aligned when the ellipsoid's shadow has reached the time scale ring. Now the sundial displays the time (9:50 EDT Eastern Daylight Time) and the longitude at which the sun is currently at noon. In the picture it is culminating above the Azores (longitude 26° W).
Solar time sometimes goes fast or slow. In order to determine our modern time with its regular intervals, you must take the "so-called" equation of time into account. You can read this off the curve (+14min on 20. Nov.) and set the time scale ring.
In "down under" , the ICARUS stands on its head. On the southern hemisphere, the Antarctic side of the world map is at the top for the viewer and the time scale runs in an anti-clockwise direction (see Rio). Nevertheless, even here the gnomon points at the polar star, even if this is never visible in Sydney .
