console.timeEnd reporting seconds as milliseconds

[HiDeoo]

🐛 Bug Report

When using console.time & console.timeEnd in a test, the logged elapsed time is indicated as being in milliseconds while actually being in seconds.

To Reproduce

Use console.time & console.timeEnd in a test:

it('should add two numbers', () => {
  console.time('test')

  expect(add(1, 2)).toBe(3);

  console.timeEnd('test')
});

Expected behavior

If the elapsed time is 7ms, I expect console.timeEnd to actually logs either:

• test: 7ms
• test: 0.007s

I'm assuming the current behavior is coming from these lines which convert the elapsed time in seconds and then log them in ms.
