Usage Guidelines
To use this command, you must be in a user group associated with a task group that includes the proper
task IDs.
The system clock keeps an “authoritative” flag that indicates whether the time is authoritative (believed
to be accurate). If the system clock has been set by a timing source, such as system calendar or Network
Time Protocol (NTP), the flag is set. If the time is not authoritative, it is used only for display. Until the
clock is authoritative and the “authoritative” flag is set, the flag prevents peers from synchronizing to
the clock when the peers have invalid times.
