You can configure your iSeries™ server as an SNTP server. This topic explains how you can use this feature to maintain time on your network.
You can use your iSeries server as an SNTP server. This enables you to configure your iSeries to act as a time server for other devices. Other SNTP clients check time by polling your iSeries SNTP server. If a client's time values do not match the iSeries SNTP server time, a time adjustment begins. The client's system time is adjusted until the required time value is reached. This can be useful for maintaining time within a network.
In Figure 1, the iSeries Server A uses the SNTP server. In this situation, the coordinated universal time (UTC) is retrieved from the iSeries server rather than being synchronized with an external time source. This internal time value is sent to all SNTP client systems (iSeries Server B and Client A) connected to it.
In addition to using the SNTP server to synchronize clocks on the network, you can concurrently run your iSeries as an SNTP client to obtain time from an outside time source. For an example, refer to Scenario: Synchronize clocks with iSeries server.
