Title:
  [HP Proliant m400] hwclock change won't take effect immediately

Status in ubuntu-kernel-tests:
  Invalid
Status in linux package in Ubuntu:
  Invalid

Bug description:
  So far this issue was only spotted on this specific hardware. And can be seen from kernel 3.13~4.12
  Not sure if this is a bug to the software or the hardware.

  Test case:
   sudo /sbin/hwclock --set --date "2/2/80 03:04:00"; sudo LC_ALL=C /sbin/hwclock

  Expected result:
   * You should see the clock has been changed to 1980

  Actual result:
   * It's still showing the current time and date. But if you check it again later (about 1 or 2 seconds) with "sudo hwclock", you will see the updated time and date.
