Logical Domains 1.3 Release Notes

Logical Domain Time-of-Day Changes Do Not Persist Across a Power Cycle of the Host

Bug ID 6590259: If the time or date on a logical domain is modified, for example using the ntpdate command, the change persists across reboots of the domain but not across a power cycle of the host.

Workaround: For time changes to persist, save the configuration with the time change to the SC and boot from that configuration.
