How to Measure the Time Between Animations

I prepared an animation scene and going to record my voice on it. To this, I need the measure the time that during between animations. I try the time module but it doesn't measure the time between animations but, guess, python's reading time. What should I do? Here is the code and console's print:

```
class KaraTahta(Scene):
def construct(self):
a = Circle()
start_time = time.time()
self.play(ShowCreation(a), run_time=2)
self.wait(3)
elapsed_time = time.time() - start_time
print(elapsed_time)
```
