System Time Configuration
System Time Overview
System time 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
Viewing the Current System Time
Select Device Management > System Time from the navigation tree, and you will enter the
System Time tab page, as shown in
Figure 1 . The current system time of the device is displayed on the
page.
