(b) A client attempts to synchronise with a time server. It records the round-trip times and timestamps returned by the server in the table below: Round-trip time (ms) Server time (hr:min:sec) 37 18:47:08.480 38 18:47:10.229 34 18:47:12.371 (i) Which of these times should it use to set its clock? (ii) To what time should it set it? (iii) The system is required to synchronise a file server's clock to within +/-1 millisecond. Can this requirement be met using Cristian's algorithm? Explain
