The failed unittest is dut_status_unittest.py
I can't reproduce the error in my local env.

maybe we added some dependancy that doesn't exist on builders. It failed on all builders, don't look like a flake.

I've reproduced failures by adding a 2-second sleep to
dut_status._validate_time_range().  The tests were meant
to pass in such a case, so the failures I saw are bugs in
the unit tests.

However, the failures I saw weren't the same set of
failures reported here, so it seems we have other bugs.

I think disabling the tests until we can have more faith
in them is a good choice in this case.

This bug has not been touched in over a year.  It is probably no longer relevant.
