 Based on The Position of the Sun, this Clock Displays Time in Shadow

Social media users are mistaking a picture that is spreading for a conventional clock. The picture actually depicts a digital sundial, which tells the time by using the shadow cast by the sun's location. Digital sundials need to be adjusted based on their location's latitude and run during daylight hours, often from 10:00 to 16:00. The distinction between sundial time and regular clock time must be understood because sundials depend on the sun's movement. Because of the Earth's orbit and slanted axis, the sun appears to move more irregularly than it actually does. Modern clocks, on the other hand, are made to operate roughly at the average speed of the sun's movement throughout the year.

Reverse image searching the image produced a website with a similar image that was identified as a 3D printed digital sundial. Additional online searches revealed that these sundials can be purchased in a variety of sizes and hues. It's important to remember that digital sundials normally run at intervals of 20 minutes and need to be adjusted for latitude. Online, there are videos showing how these digital sundials operate.

The earliest time-keeping devices were sundials, including digital sundials. Traditional sundials employ a line or triangle to represent the hour in relation to the sun's location. Digital sundials, on the other hand, cast shadows that indicate the current time using specially created items that are fashioned like numerals. These gadgets don't use energy and have no moving parts. The sundial's shape was precisely calculated to only let the right sunrays through at the right time and angle.
