    Fix GetTime.c on Darwin with clock_gettime
    
    On Darwin versions with clock_gettime, #ifdefs will prevent the
    mach-specific time functions from being used in most places, and
    the mach time headers won't be included; however, this section
    was guarded incorrectly and would still try to use them.
    
    Fixes #12195.
    
    (cherry picked from commit b7b130c5102948b38aaba723044288e16a80d492)
