It's the Hardest Clock in the World!
If you've ever looked at a clock, told the time and thought it's too easy, this is the clock for you!
It's called the Albert Clock, made by a company called MNTNT, and it's needlessly difficult!
Instead of showing numbers, it shows sums! By the time you've figured out what the time is, it isn't that time anymore!
