Error "Fortigate time is out of sync"

if the commands in the link, https://community.fortinet.com/t5/FortiGate/Troubleshooting-Tip-NTP-synchronization-issue/ta-p/195266 , show a correct date/time, the issue is cosmetic most of the time i've encountered it.

try opening the webui in incognito and the issue should go away.

Hi @nanashi 

You may want to check your local browser if it is synced with a NTP server as well. This issue can happen if the FortiGate system time differs by more than 2 minutes from the local client (browser) time.
