A clock is a device that measures and shows time, often on a wall or surface.
The idea
Say the clock says nine for its display. If it is five minutes fast, it shows a time five minutes later than the correct time.
Examples
- The clock is on the wall.
- The kitchen clock says nine.
- This clock is five minutes fast.
- She set the clock to the correct time.
- There are two clocks in the room.
- The alarm clock rang at six.

Watch out
A clock showing a particular time may be wrong; its display alone does not guarantee the actual time.
