description: |
If this configuration option is defined, then POSIX timers may not be created
to use the ${/glossary/clock-realtime:/term}. Per POSIX, this is allowed
behavior but per the FACE Technical Standard, it is not. Using POSIX timers
based on CLOCK_REALTIME (e.g., time of day) is unsafe for real-time safety
systems as setting CLOCK_REALTIME will perturb any active timers.
If this option is not defined, POSIX timers may be created to use the
CLOCK_REALTIME in compliance with the POSIX specification.
