We do have sec/nsec fields in cache_time structure, so I have
nothing against updating the msysGit port to fill that value.
I was and am just reacting to the fact that this is sold as if it
"fixes" something. It doesn't fundamentally change the fact that
mtime that does not follow the semantics Dscho mentioned in his
earlier message does not work well with Git.
Having said that, even with such a patch, as long as the system is
sufficiently fast, test and test2 will have nonoseconds identical
timestamp and you would have the same issue, no?
