How do we make the master transmit packet in the right time ?

Is is said in the etherlab book that all slaves are fixing the local
clocks according to a caluclated error.
1. who writes to the system time register ? is it the first slave or the
master ? I noticed that it possible to that in the master but this is
not the correct behavior as i understand.

2. if a master needs to transmit the N-th packet so that i will be
processed in the N-th tick of the reference (first) slave, how do i do
that ? how do i know how much time BEFORE the n-th tick to transmit the
packet ?

thank you
