An Odd Clock
Clocks come in various designs and shapes and usually, we don’t pay much attention to the details as long as they’re doing their job right. This clock, however, seems to be doing more than telling time with its different colors and directions at the bottom. Apparently, the OP spotted it at an assisted living facility and was curious to know how it worked.
Supposedly, it is for the rotation of patients suffering from bedsores. Patients should be on their right side for the red numbers, on their back for the black numbers, and their left side for the green. That’s so simple yet so effective!
