SLEM 5 clock must be configured to synchronize to an authoritative DOD time source when the time difference is greater than one second.
To configure the system clock to synchronize to an authoritative DOD time source at least every 24 hours, edit the file "/etc/chrony.conf". Add or correct the following lines by replacing "<time_source>" with an authoritative DOD time source:
server <time_source> maxpoll 16
Verify that SLEM 5 clock must be configured to synchronize to an authoritative DOD time source when the time difference is greater than one second with the following command:
> sudo grep maxpoll /etc/chrony.conf
server 0.us.pool.ntp.mil maxpoll 16
If the "server" parameter is not set to an authoritative DOD time source, "maxpoll" is greater than "16", the line is commented out, or the line is missing, this is a finding.
