small business time clock software network

File system updates carried out across several computers depend on synchronized clock times.Security mechanisms depend on consistent timekeeping across the network.Distributed procedures depend on coordinated times to ensure proper sequences are followed.Some examples of how NTP is used are the following: Why is NTP important and how is it used?Īccurate time for all devices on a computer network is important for many reasons a discrepancy of even a fraction of a second can cause problems. NTP also supports broadcast synchronization of peer computer clocks. This transaction occurs via User Datagram Protocol ( UDP) on port 123. Once synchronized, the client updates the clock about once every 10 minutes, usually requiring only a single message exchange, in addition to client-server synchronization. As a rule, six exchanges over a period of about five to 10 minutes are required to initially set the clock.The client is then able to calculate the link delay and its local offset and adjust its local clock to match the clock at the server's computer.The NTP client initiates a time-request exchange with the NTP server.The following three steps are involved in the NTP time synchronization process:
