More About time zones
Long ago, people did not have time zones. They used the sun to tell time. But as trains and cars got fast, they needed a better way. Now, we have time zones to help us.
Time zones help us in our daily lives. When we call a friend, we check the time. This way, we do not wake them up at night!
In the future, we may have new time zones. Some places may change their time. This can help with travel and fun!
