Yes - the gnulib unit test, consisting of:
Taken together, these files produce the executables test-futimens and
test-utimensat which can demonstrate compliance with POSIX. They are also
bundled as part of GNU coreutils (the version bundled with coreutils 8.2
didn't test for ctime compliance, and coreutils 8.3 hasn't been released
yet) if you use 'make -C gnulib-tests check'.
Don't work too hard, make some time for fun as well!
