Perhaps our assumption that xtime is a UTC variable is broken? If that's the case, is there a way to translate between local time zone and UTC inside the kernel? If not we have a bit of a problem since it really makes sense for Xen to work in UTC and let each guest apply its own time-zone transformation. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel |
