synchronized clocks

Coordinated time displays

Synchronized clocks are timepieces set to display the same time, coordinated through a master clock or external signal.

The concept matters in physics, where Einstein's relativity showed that clocks in different reference frames cannot remain perfectly synchronized—what seems simultaneous to one observer may not be to another.

In practical settings, synchronized clocks ensure coordination: The school's synchronized clocks all reset during the power outage.
