Using as a parameter CLOCK_REALTIME everything appears to work as expected,

What do you mean by "bogus times"?
I mean that the timing of sem_timedwait() appears to be inconsistent
with the requested values.
But I believe I've found the reason in the meantime.
According the documentation, sem_timedwait() uses CLOCK_REALTIME, and it
would appear that it can't be configured differently.
If I supply an absolute time value calculated from a different clock
source, of course I'm bound to find inconsistencies!
Thanks however.
