Next step is for the kernel team to assess whether this is a test case
issue, or a real kernel bug.

Bug description:
  The hwclock test will fail on the Power9 system "baltar" due to a
  <0.02 second difference.

  Traceback (most recent call last):

  TestFail: Failed to set hwclock back to Warthog's birthday. Output of hwclock 
is '2004-10-20 04:09:59.582146+0000'

  Didn't see this on Power8 boxes

  Sometimes it will fail because "time out waiting for time change" on the same 
  $ sudo /sbin/hwclock --set --date "2004/10/20 04:10:00"; sudo /sbin/hwclock
  hwclock: Timed out waiting for time change.

  Workaround for these is to add "sleep 1".
