TIME-3124 - NTP time local source used

Description

When only a local source is being used on a system, it might indicate that external sources are not reachable or usable. The NTP configuration and time synchronization in particular, is important for systems. It helps with properly logging the actual time, which is needed for many services. Having the right time is also important for accounting purposes and forensics. Check the NTP configuration of this system to determine the cause of this finding.

How to solve

Check the peers list (ntpq -p) to determine if there are any NTP servers configured. If they are all listed are faulty (e.g. stratum 16), check your firewall or router configuration.
