This is a vocabulary problem, then.  In the parlance we use commonly
at Nicira, a "hypervisor" is any physical machine that has some kind
of virtualization software installed.  In the parlance used in Linux
and Xen, the hypervisor refers to Xen itself, that is, to the
lowest-level software veneer over the hardware that hosts domains.

There doesn't seem to be a perfect category for the timezone, but
xen-info is not a good choice.  "system-logs" may be the best choice
because in practice we only really care about the timezone when we are
reading the system logs.

Thanks,

Ben.
