description: |
  If this configuration option is defined, then POSIX timers may
  not be created to use the CLOCK_REALTIME. 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.
