Big Sur - Enable macOS Time Synchronization Daemon (timed)

Information

The timed service _MUST_ be enabled on all networked systems and configured to set time automatically from the approved time server.

This rule ensures the uniformity of time stamps for information systems with multiple system clocks and systems connected over a network.

Solution

This is implemented by a Configuration Profile.

mobileconfig profile info:

com.apple.ManagedClient.preferences:
 com.apple.timed:
 TMAutomaticTimeOnlyEnabled
 True
