Troubleshooting Tip : How to fix FortiAnalyzer NTP High Latency

First Info:

NTP Server Address: 10.10.xx.xx.

Stratum: 4 (indicates a fairly reliable time source).
Time Offset: -14us.
Network Delay: +/- 72ms.

Conclusion: This device has good NTP synchronization with minimal time offset.

Second Info :
NTP Server Address: 1.232.xxx.xx.

Stratum: 4.
Time Offset: +1290ms (1.29 seconds).
Network Delay: +/- 10.1s.

Conclusion: This device is synchronized with the NTP server; however, there is a significant time offset (1.29 seconds) and high network delay (10.1 seconds), which may affect time accuracy.

Recommendations:

1. Check the network connectivity of the second device to ensure good NTP server reachability.
2. Consider switching to a closer or more stable NTP server to reduce latency and time offset.
3. Adjust NTP settings on the FortiAnalyzer, such as increasing the polling interval or using a local NTP server.

To increase the polling interval :

config system ntp
    edit 2
        set server pool.ntp.org
        set minpoll 8
        set maxpoll 10
    next
end

However, if there is still an issue, consider to:

1. Fix network latency.
2. Use a local/internal NTP server.
