 Thank you so much!

I tried the patch in http://lists.xensource.com/archives/html/xen-devel/2010-07/msg00477.html. And i can get the right wallclock time through wc_sec, wc_nsec and hypercall HVMOP_get_time now.

BTW, I still do not know why I always hit issue several days ago: wc_sec kept zero value on boot, and changed to non-zero value if i changed clock time manually in windows vm . But things went well after
i rebooted dom0. Maybe something wrong with the system at that time.
