This is currently done in
https://github.com/mongodb/mongo/blob/master/src/mongo/util/timer-inl.h:
... #elif defined(_POSIX_TIMERS) and _POSIX_TIMERS > 0 and defined(_POSIX_MONOTONIC_CLOCK) and _POSIX_MONOTONIC_CLOCK > 0 // On systems that support the POSIX clock_gettime function, and the "monotonic" clock, // use those. #include "mongo/util/timer-posixclock-inl.h" #else ...
It would be desirable to do this check during the SCons configuration phase and set a MONGO_HAVE_POSIX_MONOTONIC_CLOCK preprocessor variable if the "monotonic" clock is available.
