clock_getres

Gnulib module: —
Portability problems fixed by Gnulib:
Portability problems not fixed by Gnulib:
clock_gettime
, i.e., the minimum distance between
differing timestamps. For example, on AIX 7.2 it returns 10
milliseconds even though the clock resolution is 1 microsecond.
Conversely, on GNU/Linux it typically returns 1 nanosecond even
though the clock resolution may be greater.
The Gnulib module gettime-res
is a partial substitute; it implements
the CLOCK_REALTIME
functionality of clock_getres
,
and fixes the too-high resolution bug of platforms like AIX 7.2.
