A clock knows what time it is because someone tells it! Imagine a clock like a little robot that needs instructions. When you set the time, you're giving it directions, like a secret code. If it's connected to something else, like a radio or a phone, it can keep checking in and update itself. That’s how clocks know what time it is without thinking.
Examples
- Your alarm clock knows the time because you set it before going to bed.
- A smartwatch updates its time by listening to your phone’s signal.
- The grandfather clock in your house ticks correctly because you told it what time it was.
