yes but those guesses have "smudge windows" which are functions of the physical distance between relevant nodes
if you want to make assertions about order between events from a set of nodes, and you want to use per-node physical clocks to determine that order, then even if those clocks are perfectly synchronized, order can only be decided when the light-cones of all nodes intersect, which is the maximum distance between any two nodes times the speed of light
7ms works for up to 2098km, that's in the best case
