Re: Cygwin with clock_gettime and CLOCK_MONOTONIC - gives always 0

Works fine for me with the current Cygwin 1.7.17, and the upcoming
Cygwin 1.7.18:
     if (!clock_gettime (CLOCK_MONOTONIC, &tp))
       printf ("tv_sec = %ld, tv_nsec = %ld\n", tp.tv_sec, tp.tv_nsec);
...
   tv_sec = 0, tv_nsec = 29920

Where is actually the source code of the clock_gettime, which Cygwin uses? I thought that it was newlib. But looking at
http://sourceware.org/cgi-bin/cvsweb.cgi/src/newlib/libc/sys/linux/clock_gettime.c?cvsroot=src
the code should return -1 for "clock_gettime (CLOCK_MONOTONIC" as CLOCK_MONOTONIC (= 4) is not handled, only CLOCK_REALTIME (= 1, according to src/newlib/libc/include/time.h).

However, as both you and Angelo get a zero return value, I must look at the wrong file.
