Configuring the system time
NOTE:
•
The firewall modules synchronize the time with the NTP server (a primary networking device installed
with a firewall module) through NTP. The system time resets to 12:00:00, 26, April, 2000 each time it
starts, and is synchronized to the correct time after the system starts up.
•
After a firewall module is configured with NTP synchronization, it sends a NTP time request every 64
seconds. If it finds that its time is asynchronous with the NTP server, the firewall module synchronizes its
time with the NTP server in a few minutes.
•
The configurations about
system time are suitable for the firewall chassis.
Configuring the system time in the web interface
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.
