Description Yaniv Kaul 2012-10-11 04:15:11 EDT
Description of problem:
Currently we ignore the fact that there might be time difference between the host and the VM's clocks. We should store the diff and use it in the command line (something like -rtc base=2012-10-09T13:22:57)

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Look at a hypervisor qemu command line when running an instance. It lacks this offset calculation.
Actual results:

Expected results:

Note: currently Nova uses -rtc base=utc
Comment 11 Daniel Berrange 2013-09-19 13:39:24 EDT
No work was done in this upstream - there's not even a blueprint for it at this time.
Comment 13 Russell Bryant 2014-08-12 10:05:45 EDT
It's too late to do this for Juno, but it's something we could do for Kilo.
