Sure, but the test is aimed at checking whether strace's time accounting (-c option) works correctly and such a significant offset (more than 20%, on a single nanosleep call waiting for 1 second) may mean that something going wrong. Frankly speaking, i haven't seen such a big skew on x86_64 systems with recent kernels even with rather intensive I/O and quite high LA (and it never occurred on a multitude of OBS builds i ran on x86_64, ppc and arm), so i assumed, taking into account previous report, that it might be something more persistent and complex than just high system load.
