Hi, futimens is broken on GNU Hurd: it does not support UTIME_NOW or UTIME_OMIT. I filed a bug about that here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=762677 The Gnulib test suite already detects this: ../../gltests/test-futimens.h:138: assertion 'st3.st_atime == Y2K' failed I have a patch which fixes this test failure, but I don't remember the status of my copyright assignment and I don't want a fix for this to accidentally get stuck on that. Perhaps I can just describe it? On the Hurd, HAVE_UTIMENSAT is undefined but HAVE_FUTIMENS is defined. Before calling futimens, fdutimens must check whether UTIME_NOW or UTIME_OMIT was used (i.e. adjustment_needed > 0). If so, it should resolve them to real times.
