Clocks don’t know the time, they just count seconds, minutes, and hours. But some clocks get help from other things, like radio waves or the internet, to check in and stay accurate. It’s like having a friend who tells you what time it is every day so you can keep track too.
How Clocks Stay Synchronized
Some clocks have a special signal they listen for. When that signal comes in, they update their time instantly. This helps them always match the real time, no matter where you are.
Examples
- A wall clock in a remote village uses a small radio to listen for signals from the city.
