JClock VII (#81)

Jonathan Frech,

This alternative clock is not really readable by human. It calculates the first 144⁠¹ primes, assigns 60 of them to every possible second, 60 to every possible minute and 24 to every possible hour.
Multiplying those three primes for a given time results in a composite num­ber representing said time. Using in­te­ger factorization, you then can get the three primes back, map them to seconds, minutes and hours, and by doing so cal­cu­late the time.


[1]This num­ber is the sum of 60 seconds, 60 minutes and 24 hours.
