The double precision timeScale-independent time for this frame (Read Only). This is the time in seconds since the start of the game.
Double precision version of unscaledTime. This offers more precision than a float or single value, particularly
over extended periods of real-world time. In almost all cases, use the unscaledTimeAsDouble equivalent over unscaledTime.
When called from inside MonoBehaviour's FixedUpdate, it returns the unscaled fixed time.
Returns the same value if called multiple times in a single frame. Unlike timeAsDouble this value is not affected by timeScale.
