Internet time
The System|Internet Time page is used to configure the time of day on the
ONU. The time is retrieved from one of the SNTP servers configured on the
page. The Time Zone is used to set the time to local time. Note that the ONU
does not automatically compensate for Day Light Saving Time.
DHCP Option 42 is supported. If a DHCP offer uses Option 42 to specify an
SNTP server and time zone offset, it will automatically configure the SNTP
attributes on this screen.
The zNID 24xx maintains the time of day for applications such as Syslog. The
time is acquired from one of five specified time servers. If no time server can
be found, the system will default to January, 1. The system allows for up to
five time servers to be configured. If the first server is unreachable, the ONU
will try the next server. If that is not available, it will try the next one, and so
on. The configuration of the time client is shown below.
