"Wrapping Time"?!?

I have heard of the concept of “wrapping time” in order to control time in unity better (for pause screen, speeding time, etc…),
but i cant really understand what it means. Can somebody please explain?

If you want to have the slow motion effect, or to just speed things up you can use:

Time.timeScale;

Example:

Time.timeScale = 0.5; // game is in slow motion.
