My understanding is that this clock should return the execution time
consumed for the thread. I suspect that returning the thread id for this
cpu clock id will work. In clock_gettime, check for the hard coded clock
IDs, then look this up as a thread id and if it is valid, return the cpu
time used.

You can't set this IMO but check the POSIX standard.
