Clocks work together like a team. Imagine you and your friend both have watches, but they’re not perfectly in sync. To fix that, someone checks the time on a super-accurate clock, called an atomic clock, and tells everyone else what time it is. This way, all clocks across the world can match up with each other.
Examples
- Your phone updates its clock from a nearby tower every day.
- A school in Japan stays in sync with one in New York using satellites.
- You can video chat with someone on the other side of the world without time differences.
