Configuring system time
Configure a correct system time so the device can work with other devices correctly.
The device supports setting and displaying the system time, and setting the time zone and daylight
saving time through manual configuration and automatic synchronization of NTP server time.
An administrator cannot 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. NTP, however, allows quick clock synchronization within the entire network and
ensures a high clock precision.
Defined in RFC 1305, NTP synchronizes timekeeping among distributed time servers and clients.
NTP runs over the User Datagram Protocol (UDP), using UDP port 123.
NTP enables you to keep consistent timekeeping among all clock-dependent devices within the
network so that the devices can provide diverse applications based on the consistent time.
Setting the system time
1. From the navigation tree, select System Management > System Time.
The System Time page appears. On the upper part of the interface, the current system time is
displayed.
2. Set the system time as described in Table 196.
