The Semaphore supports only CLOCK_REALTIME, which has issues when the system time is changed. The POSIX ConditionVariable has an attribute to specify the clock and also accepts CLOCK_MONOTONIC.
On Systems that support POSIX condition variables, those should be used with the CLOCK_MONOTONIC instead of the Semaphore in combination with the AdaptiveWait.
