Sorry did not realize that all the comments were not correctly mirrored
over. A launchpad bug was reported by the Ubuntu kernel team as a result
of their testing in the lab. We were not sure if this was a BMC issue, a
hardware issue or kernel bug, so there is no github report as of now. If
you think this is related to the BMC I can open a github bug. Also
please tell us how to open bugs for BMC on Bostons.

There seems to be a delay between setting the hwclock and reading from it.
ubuntu@tiselius:~$ sudo /sbin/hwclock --set --date "2004/11/21 04:10:00"; sudo
strace -e ioctl "/sbin/hwclock"
ioctl(4, RTC_UIE_ON) = -1 EINVAL (Invalid argument)
ioctl(4, RTC_RD_TIME, {tm_sec=0, tm_min=10, tm_hour=4, tm_mday=21, tm_mon=10,
tm_year=104, ...}) = 0
ioctl(4, RTC_RD_TIME, {tm_sec=0, tm_min=10, tm_hour=4, tm_mday=21, tm_mon=10,
tm_year=104, ...}) = 0
when the hwclock command fails, the ioctl that fails is RTC_RD_TIME..
but running it with --verbose probably gives it just enough time to
complete the sync.
Or you could use the command as follows:
ubuntu@tiselius:~$ sudo /sbin/hwclock --set --date "2004/11/22 04:10:00"; sudo
/sbin/hwclock --delay=0.5
2004-11-22 04:09:59.898618+00:00
ubuntu@tiselius:~$
== P9 Witherspoon ==
On the Witherspoon the hwclock does not seem to set at all.

Title:
hwclock test failed on Power9 due to 0.x sec differences / time out
waiting for time change
Status in ubuntu-kernel-tests:
New
Status in The Ubuntu-power-systems project:
Incomplete
Status in linux package in Ubuntu:
Incomplete
Bug description:
The hwclock test will fail on the Power9 system "baltar" due to a
<0.02 second difference.

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
node:
$ 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".
