Review comment:
This changes the behavior because it previously would print a DATE, now
it's just printing a number.

> Hello,
> I found that System.currentTimeMillis() can be used here instead of new
> Date.getTime().
> Since new Date() is a thin wrapper of light method
> System.currentTimeMillis(). The performance will be greatly damaged if it is
> invoked too much times.
> According to my local testing at the same environment,
> System.currentTimeMillis() can achieve a speedup to 5 times (435 ms vs 2073
> ms), when these two methods are invoked 5,000,000 times.
