System time
You need to configure a correct system time so that the device can work with other devices properly.
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 cannot keep time synchronized among all the devices within a network by changing the
system clock on each device, because this is time-consuming task and cannot guarantee clock precision.
Defined in RFC 1305, the Network Time Protocol (NTP) synchronizes timekeeping among distributed
time servers and clients.
NTP can keep consistent timekeeping among all clock-dependent devices within the network and ensure
a high clock precision so that the devices can provide diverse applications based on consistent time.
