You can see this clearly from the following disasters caused by out-of-sync timing:

Unjust Speeding Tickets

If two cameras on a highway have a 1-second time difference, the calculated vehicle speed can jump from 100km/h to 200km/h, landing you with an unfair speeding ticket out of nowhere.

Robot Collisions

When two robotic arms work together to lift a fragile item, if the "left hand" lags 0.01 seconds behind the "right hand", the item will shatter, or the two machines will crash into each other.

Mass Power Grid Blackouts

When a fault occurs in the power grid, tens of thousands of sensors across the province record data. If their timestamps are not aligned, engineers cannot pinpoint where the fault first broke out, making it impossible to restore power quickly.
