mentions the same unit - "ppm" - it doesn't explain what that means.

What does "ppm" stand for ?

microseconds per second.

Hi Martin,

Ah, I see! From Google there was a link that referenced PPM with a different: ntpd implementation and it mentioned "Parts Per Million", but I was confused by that as I have only heard of Parts Per Million with pollution / chemistry ... but microseconds per second makes sense.

Thanks!
