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.
