If the clocks are programmed to know their distances from each other, you can account for that.

If the clocks are programmed to know their distances from each other, you can account for that.
- Dylan16807 5y agoYou can, but is there any practical effect?
- maronato 5y agoImagine that the same message reaches more than one servers. Which one should record it? If they all are in sync you just use the one that received the event at the lowest timestamp
- Dylan16807 5y agoNow imagine the same scenario but one of the servers is eight feet to the left. Does it matter that a different server picked up the message first? Now what if the server just thinks it's eight feet to the left because the clock is out by several nanoseconds? Can't you just ignore that, and still use the server that got the lowest timestamp? What's the practical difference? When the servers can communicate in x amount of time, the question was specifically about clock drift "much smaller than" x.
