clock_getres(2), clock_gettime(2), and clock_settime(2) first appeared
in POSIX.1-1996.[1]  SUSv2 incorporates POSIX.1-1996, so listing both is
redundant.
Technically these functions came from POSIX.1b (1003.1b-1993), which
was a set of optional realtime extensions to POSIX, published as a
separate document.  POSIX.1-1996 integrated them into the main
standard (1003.1-1996) as part of a Timers extension.  In 1997 X/Open
adopted them to SUSv2 as part of their own X/Open Realtime extension,
which includes the POSIX Timers extension and other extensions that
had been added to POSIX from POSIX.1b.
Thanks!  For now, I think I'll take the patch, even if the commit
message is factually incorrect.  We can then do a future round of
patches researching those less common POSIX extension standard.
Good to know.  I'll be sure to phrase my patch descriptions more
carefully from now on to prevent such inaccuracies.
