36 minutes agomechanical clock with rotating discs can tell what time it is on other planets
Since every planet spins at a different speed, the gears are built with different ratios: Earth takes about 24 hours to spin once, Mars takes about 24.6 hours, Jupiter spins much faster, and Saturn spins fast too. Because of this, each dial shows the real day cycle of that planet, so the clock doesn't calculate time digitally.
