Hello,
I failed to read host time by using do_clock_host_realtime, so I tried
clock_gettime(CLOCK_HOST_REALTIME) by executing "clocktest -C 2", but I got:
== Tested clock: 2 (<unknown>)
CPU ToD offset [us] ToD drift [us/s] warps max delta [us]
--- -------------------- ---------------- ---------- --------------
0 0.0 0.000 0 0.0
clock_gettime failed for clock id 2
Anyone knows what's the problem?
Thanks for help!
regards,
Chris

As we know, the answer to all questions is 42, also to this one:
#define CLOCK_HOST_REALTIME 42
