I'll see about putting together a patch then.
Is it OK to simply have wc_sec altered by an optional, per domain time offset from UTC in seconds (hence binary no change to the interface), or do you think there should be another field provided that is the offset, leaving wc_sec unmodified?

I guess it might be useful to be able to configure a 'wallclock offset
in seconds' for a domain. It would need to be implemented in Xen and set
via a dom0 op.
