System Time Configuration
Overview
The system time module allows you to display and set the device system time on the Web interface.
The device supports setting system time through manual configuration and automatic synchronization
of NTP server time.
An administrator can by no means keep time synchronized among all the devices within a network by
changing the system clock on each device, because this is a huge amount of workload and cannot
guarantee the clock precision.
Defined in RFC 1305, the Network Time Protocol (NTP) synchronizes timekeeping among distributed
time servers and clients. NTP allows quick clock synchronization within the entire network and ensures
a high clock precision so that the devices can provide diverse applications based on the consistent time.
Configuring System Time
Select
System
>
System Time
from the navigation tree to enter the system time configuration page, as
shown in Figure 1-1 . On the upper side of the interface, the current system time and clock status are
displayed, and you can click

to refresh the displayed content; on the lower side of the interface,
you can set the system time.
