Please don't CC me or cgf. We're subscribed to the Cygwin list anyway.

Works fine for me with the current Cygwin 1.7.17, and the upcoming
Cygwin 1.7.18:
$ cat > ct.c <<EOF
#include <stdio.h>
#include <time.h>
int
main ()
{
struct timespec tp;
sleep (1);
if (!clock_gettime (CLOCK_MONOTONIC, &tp))
printf ("tv_sec = %ld, tv_nsec = %ld\n", tp.tv_sec, tp.tv_nsec);
sleep (1);
if (!clock_gettime (CLOCK_MONOTONIC, &tp))
printf ("tv_sec = %ld, tv_nsec = %ld\n", tp.tv_sec, tp.tv_nsec);
sleep (1);
if (!clock_gettime (CLOCK_MONOTONIC, &tp))
printf ("tv_sec = %ld, tv_nsec = %ld\n", tp.tv_sec, tp.tv_nsec);
sleep (1);
if (!clock_gettime (CLOCK_MONOTONIC, &tp))
printf ("tv_sec = %ld, tv_nsec = %ld\n", tp.tv_sec, tp.tv_nsec);
}
EOF
$ gcc -o ct ct.c
$ ./ct
tv_sec = 0, tv_nsec = 29920
tv_sec = 1, tv_nsec = 15866090
tv_sec = 2, tv_nsec = 28048880
tv_sec = 3, tv_nsec = 42100530
