[Question] How do I enable millisecond diff?

The debug package shows a very nice millisecond diff feature:

But for some reason, in my logs, I don't see it. (Although I do see timestamps). I prefer seeing millisecond diff, over timestamps. How can I enable the millisecond diff? I'm using debug 4.3.4.

It might have to do with the fact that my logs are printing to docker-compose output? Not sure.
