TIME-3104 - Running NTP daemon


Proper time synchronization is important for authentication services, forensics and troubleshooting. Therefore a time daemon (like ntpd) should be running, or a scheduled task to sync time (like ntpdate).



How to solve

Configure a NTP daemon to keep the time in sync with a time server. Most distributions have a "ntp" package available, which can be configured to regularly update the time. If you don't have an internal time server, we suggest to have a look at the website, for time servers in your region.
