Ephemeris Time
A clock about time and light.
Ephemeris Time honors the powerful relationship between time and light.
It’s a connection that goes back 5,000 years to the implementation of the first sundials, and whose profound intimacy Lorentz, Poincaré, and Einstein strove to reveal in the 20th century.
Time told by light and shadow.
The time tells the light where to fall, and where the light falls tells you the time. It’s the way almost every clock works—-this one is just very frank about it.
The wall itself is the clock’s face.
Each of two nested plastic shells contains its own gnomon, projecting an hour hand and minute hand as they occlude the LED backlight, while the mounting nail casts the twelve o’clock mark.
