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.
