Configuring Current System Time

This section describes how to configure the current system time.

Configuring the System Time Manually

To configure the system time manually, take the following steps:

1. Select System > Date & Time from the menu bar.
2. On the Current System Time tab, configure the options as below:
   • Sync with local PC: Click Synchronize to synchronize the system time with the time of your local PC.
   • Time zone: Select the time zone from the drop-down list.
   • Date: Specifies the date.
   • Time: Specified the time.
3. Click OK to save your settings.

Configuring NTP

The system time may affect the establishment time of VPN tunnel and the schedule, so the accuracy of the system time is very important. To ensure the system is able to maintain a accurate time, the security device allows you to synchronize the system time with a NTP server on the network via NTP protocol.

To configure NTP, take the following steps:

1. Select System > Date & Time from the menu bar.
2. Under NTP server in the Date & Time dialog, configure the options as below:
   
   • Preferred server: Type the server name or IP address. The system will synchronizate with the first preferred server. You can specify up to 3 servers.
   • Key: Select a key from the Key drop-down list. If you enable the NTP Authentication function on the NTP server, you have to specify a key.
   • Source interface: Select an interface for sending and receiving NTP packets.
3. Under NTP parameters, configure the options as below:
   
   • Enable: Select the Enable check box to enable the NTP function. By default, NTP function is disabled.
   • Authentication: Select the Authentication check box to enable the NTP Authentication function.
   • Sync interval: Type the interval value. The device will synchronize the system time with the NTP server at the interval you specified to ensure the system time is accurate.
   • Max adjustment: Type the time value. If the time difference between the system time and the NTP server's time is within the max adjustment value you specified, the synchronization will succeed, otherwise it will fail.
4. Click OK to save your settings.
