Show timings in milliseconds

[hph]

It makes more sense to show the timings in milliseconds than in seconds. Examples (taken from the images in the README):

• 0.00200009346008 -> 2 ms.
• 0.0 -> 0 ms.
• 0.000999927520752 -> 1 ms.

Timings won't matter if they're below 1 ms anyway. If you still want to keep them you might want to make them clearer.

Made the assumption that these were actually in MS, whoops!
