Thanks for info. Out of curiosity: I suppose the different approach from the
exact value for LTP Linux tests fixed in 5c0e414511 (which use lib/tst_clocks.c)
is because POSIX tests can be tested for other Unix like tests? Is the POSIX
testsuite intended for BSD or any unix like kernels/OS? If yes, I wonder if
anybody does (and if it even compiles).

Kind regards,
Petr
