在统一中我如何检查和打印事件发生所需的时间？

Question

我有这个我创建的运动代码我想检查玩家跳跃需要多少时间，跳跃后回到地面以及总时间我该如何计算并打印出来？如果玩家跳跃会影响我想知道的任何事情，还有一个动画设置为播放

        //Look around
        Quaternion rotationDelta = Quaternion.Euler(new Vector3(0, Input.GetAxis("Mouse X") * MouseSensitivity, 0));
        targetRotation = rb.rotation * rotationDelta;
