View this topic to learn how to use the Simple Network Time Protocol
(SNTP) application for time maintenance.
If you do not have a time maintenance application of your own or you want
to take advantage of the IBM-supplied time maintenance application, you can
use SNTP.
For more information about the various ways you can configure SNTP, see
the following topics:
- SNTP client
- Specifies how to configure SNTP as a client. When SNTP is configured as
a client, the iSeries™ server
retrieves a time value from an external time source. You can specify from
which source to retrieve the time value. This external time value is compared
to the iSeries system
time. If the iSeries time
value does not match the external time source, a time adjustment begins. The iSeries system
time is adjusted until the desired time value is reached.
- SNTP server
- Specifies how to configure SNTP as a server. When SNTP is configured as
a server, the iSeries server
sends its system time to the clients connected to it. 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 desired time value
is reached.
- Scenario: Synchronize clocks with iSeries server (SNTP as a client and
server)
- Specifies how to configure SNTP to function as a client and as a server.
In this situation, the system specified as the SNTP client server retrieves
the time from an external time source and uses that to maintain its local
system time. The local system time is then also provided to other systems
connected to it. The local system's time value is compared to each client's
system time. If any of the system's time values differ from the local system
time on the server specified as the SNTP server, a time adjustment begins.
