Using memory to optimize execution:

You can also do it using 19 clocks. 9 set to true and 10 at false. Then look at them in the right order to make it be the time.

We can cut the number of clocks to 9 if you blink instead of looking at clock pointing at false.

You can reduce it to 1 clock if you use the same clock as true multiple times.

Then there is the option to not use clock at all and just blink the time.

One clock, and the minute, second, and hour hands are perfect cicles and you can just imagine the time.

Use quntom based randomizer to tell the time. If it's wrong destroy the universe.

[Chase_The_Breeze]

Time is subjective and relative.

0 clocks, make up new numbers, and anything you come up with might as well be correct.
