+ Auxiliary POSIX clocks are clocks which can be steered
+ independently of the core timekeeper, which controls the
+ MONOTONIC, REALTIME, BOOTTIME and TAI clocks. They are useful to
+ provide e.g. lockless time accessors to independent PTP clocks
+ and other clock domains, which are not correlated to the TAI/NTP
+ notion of time.
