If different between times on computers are highest than few second is better set to clock by ntpdate program if computer boots. This case is possible to use witting master computer address to file /etc/ntp/step-tickers or write command ntpdate <master> on end of /etc/local file.
Hint: ntpd synchronize time after several minute, sometimes you'll have to very patient.
