I find it wasteful to make a simple clock running a full-scale Linux distro just to fetch and display the time. And it's running Python too, which is an interpreted language which is a 100 times slower than C or assembly.

I didn't look at the code but if it's not interrupt driven it will be wasting even more power.

The beauty of living in the modern age is that there are times when you don't have to worry about being wasteful. This project is a perfect example.

It's likely that the most power consuming part of the clock is the display.
