Description
Time synchronization must be enforced on all networked systems. This rule ensures the uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. Satisfies: SRG-OS-000355-GPOS-00143, SRG-OS-000356-GPOS-00144, SRG-OS-000785-GPOS-00250

Check Text (C-268427r1038944_chk)

Verify the macOS system is configured to enforce time synchronization with the following command: /usr/bin/osascript -l JavaScript << EOS $.NSUserDefaults.alloc.initWithSuiteName('com.apple.timed')\ .objectForKey('TMAutomaticTimeOnlyEnabled').js EOS If the result is not "true", this is a finding.

Fix Text (F-72358r1034220_fix)

Configure the macOS system to enforce time synchronization by installing the "com.apple.timed" configuration profile.
