4. Sun dial: This is a device that measures time using the position of the sun in the sky.

5. Atomic clock: This is a highly accurate clock that measures time using the vibrations of atoms.

6. Computer clock: This is the clock that is built into a computer and is used to measure the amount of time that has elapsed between events.

7. GPS time: This is a time measurement system that uses signals from GPS satellites to calculate the time.

8. Network time protocol (NTP): This is a protocol used to synchronize the clocks of computers over a network.

9. Real-time clock (RTC): This is a clock that is built into a computer or other electronic device and is used to keep track of the time even when the device is turned off.

10. Time stamping: This is a method of adding a time stamp to data to indicate when it was created or modified.
