Ok, saw it now. But doing it after link() is a bit too late. It's
possible that another process could have seen the file at that point
with the wrong timestamp. Also I don't think link() should update mtime,
and it doesn't with me, neither with ext3 nor with NFS.

What if you try it manually?

stat somefile
ln somefile somefile2
stat somefile2

Only "Change" time should have changed, "Access" and "Modify" should be
the same. Or if you don't have stat, I guess ls -l is enough as long as
the mtime is old enough..
