Suppose we have two points,
B, each point has its own clock.
We are able to send messages between
B, the message takes some random delay to be delivered:
$$min < delay < max,$$for each message the actual delay is unknown.
In this setup:
- Can we sync clock at this points perfectly?
- Can we prove that it is impossible to sync perfectly?
- Can we prove that it is impossible to sync this clock with a precision, which is better than some $f(min, max)$? (In other words, that after any sync process, this clock will still have difference at least $f(...)$)
Precision is the difference between this clock after actually syncing.
