For my own information, is 'time' the only standard function that uses a 
clock other than CLOCK_REALTIME and so can be out-of-sync with 
timespec_get? What about gettimeofday, futimens with UTIME_NOW, or 
timestamps set by modifying files?

My idea is to go through the apps I help maintain, and make sure that 
they never call 'time' anywhere that it's important that a timestamp be 
in sync with with the rest of the system, since Glibc 'time' is out of 
sync in that way.
