XSI_ADVANCED_REALTIME

The XSI_ADVANCED_REALTIME option group indicates that the _POSIX_CLOCK_SELECTION, _POSIX_CPUTIME, and _POSIX_MONOTONIC_CLOCK options are enabled.

Enable this option group with CONFIG_XSI_ADVANCED_REALTIME.

An implementation that claims conformance to this option group shall also support the POSIX_TIMERS option group.
