> not really, because except for rare RTOS systems used in ABS breaking systems and such, there is no such thing as a 1ms granularity. It may be that your best resolution is 1ms, but you might wake up 2500ms later after disk swap is done, or at half the expected sleep time because of some Unix signal and you don't care to rewait after that, or just general noise of kernel processes, interrupts, TLB misses, etc.

While I agree with that, I think it is unrelated to the discussion here. Because that issue exists in any code, including https://github.com/quicwg/base-drafts/issues/2670#issuecomment-490985340. I am saying that the value returned by `now` is in milliseconds.
