Steve Loughran commented on HADOOP-12603:
-----------------------------------------
..given this is checking local FS behaviour, and that's an implementation
detail we can't address, why not just kill these tests. They don't show
regressions in our code, merely demonstrate that different filesystems behave
differently.
if they are to be retained, then they should go into the AbstractFSContract
tests, and {{LocalFSContract}} can determine the expected timestamp range on
symlinks, the way it already determines FS permission model and case
sensitivity.

> I have observed this test failure a few times in the past. When it fails, the
