[Bug 1157914] Re: time never catches up to reality after VM sleep

[Martin Pitt]

This is first and foremost a QEMU or linux bug (not sure which), it
should really update its internal time after suspend. But I suppose ntp
could also listen to resume events (perhaps through pm-utils' /usr/lib
/pm-utils/sleep.d/ scripts); although this should already be covered by
its existing if-up.d script, i. e. as soon as the VM gets back online
after resuming /etc/network/if-up.d/ntpdate ought to run. It doesn't in
your case?

Title:
  time never catches up to reality after VM sleep

Status in “qemu” package in Ubuntu:
  New

Bug description:
  When I run Ubuntu in a VM, then sleep the VM for a little while, I
  expect time to eventually catch up to reality, because I have "Set the
  time ... Automatically from the Internet".  However, time never does
  catch up.

  I can trigger a catch up by toggling the datetime indicator to
  "Manually", wait a little bit, then toggle back to "Automatically from
  the Internet".  I may have to do this a couple of times to fix the
  time.

  This tells me that it's not a problem with the VM environment
  specifically, but a problem with coordinating time over the internet.
