Answer 2

Explanation:

Planck time is the time light takes to travel one Planck length. Theoretically, this is the smallest time measurement that will ever be possible. Smaller time units have no use in physics as we understand it today. The TU (for Time Unit) is a unit of time defined as 1024 µs for use in engineering.
