Что быстрее: MotionEvent.getEventTime() или System.currentTimeMillis() ⇐ Android

[Anonymous]

Я хотел бы измерить время, прошедшее между MotionEvent.ACTION_DOWN и MotionEvent.ACTION_UP. Какой из методов эффективнее:
public boolean onTouchEvent(MotionEvent event) {
long msEventTime = event.getEventTime();

switch (eventAction) {
case MotionEvent.ACTION_DOWN:
msTouchDown = msEventTime;
return;
case MotionEvent.ACTION_UP:
msTouchUp = msEventTime;
duration = msTouchUp - msTouchDown;
return;
}
}

или этот метод
public boolean onTouchEvent(MotionEvent event) {
long msEventTime = System.currentTimeMillis();

switch (eventAction) {
case MotionEvent.ACTION_DOWN:
msTouchDown = msEventTime;
return;
case MotionEvent.ACTION_UP:
msTouchUp = msEventTime;
duration = msTouchUp - msTouchDown;
return;
}
}
