Set system time by synchronizing with an NTP server

For accurate time, use an NTP server to set system time. Synchronized time facilitates auditing and consistency between expiry dates used in expiration of certificates and security protocols.

From the GUI go to System > Settings > System Time and select Synchronize with NTP Server. By default, this causes FortiOS to synchronize with Fortinet's FortiGuard secure NTP server.

From the CLI you can use one or more different NTP servers:

config system ntp

set type custom

set ntpsync enable

config ntpserver

edit 1

set server <ntp-server-ip>

next

edit 2

set server <other-ntp-server-ip>

end
