Title:
  clock sync via NTP causes commissioning or deployment failures

Status in cloud-init:
  New
Status in MAAS:
  New

Bug description:
  We have a mixed OS environment under MAAS control. When we release a
  system in MAAS previously running windows, the hardware clock will be
  set to local time (CST) which is just what Windows does natively. When
  we go to recommission the system and then redeploy it with Ubuntu, it
  PXE boots into Ubuntu and then timedatectl will sync with NTP, causing
  the clock to skip ahead 5 hours, which in turn causes cloud-init to
  fail and thus the commissioning or deployment task will fail. Here's
  an example log:

  2021-02-03T14:51:38+00:00 2HQCR33 cloud-init[2249]: 2021-02-03 14:51:38,922 - util.py[WARNING]: Running module apt-configure (<module 'cloudinit.config.cc_apt_configure' from '/usr/lib/python3/dist-packages/cloudinit/config/cc_apt_configure.py'>) failed

  At this moment, MAAS will immediately mark the task as failed, even if
  the later commissioning or deployment steps do continue to run on the
  host.
