System Settings : Dashboard : System Information widget : Configuring the system time
 
Configuring the system time
You can either manually set the Fortinet system time or configure the Fortinet unit to automatically keep its system time correct by synchronizing with a Network Time Protocol (NTP) server.
 
For many features to work, including scheduling, logging, and SSL-dependent features, the Fortinet system time must be accurate.
To configure the date and time
1. Go to System Settings > General > Dashboard.
2. In the System Information widget, in the System Time field, select Change. The Change System Time Settings dialog box appears, see Figure 37.

3. Configure the following settings to either manually configure the system time, or to automatically synchronize the Fortinet unit’s clock with an NTP server:
System Time
The date and time according to the Fortinet unit’s clock at the time that this tab was loaded, or when you last selected the Refresh button.
Time Zone
Select the time zone in which the Fortinet unit is located and whether or not the system automatically adjusts for daylight savings time.
Set Time
Select this option to manually set the date and time of the Fortinet unit’s clock, then select the Hour, Minute, Second, Year, Month, and Day fields before you select OK.
Synchronize with NTP Server
Select this option to automatically synchronize the date and time of the Fortinet unit’s clock with an NTP server, then configure the Syn Interval and Server fields before you select OK.
 
Sync Interval
Enter how often in minutes the Fortinet unit should synchronize its time with the NTP server. For example, entering 1440 causes the Fortinet unit to synchronize its time once a day.
 
Server
Enter the IP address or domain name of an NTP server. To find an NTP server that you can use, go to http://www.ntp.org.
 
4. Select OK to apply your changes.
