Hello! Exactly same problem after my upgrade from snv_126 to snv_129! On two HW identical servers (both running as xVM dom0) time worked O.K. up to and with snv_126. After upgrade to snv_129 both clocks jumped backward for 2 hours. I followed instructions on that blog: http://southbrain.com/south/2009/09/rtc-sun-xvm-wrong-timezone-off.html and on one of servers time went to normal but on the other time is still off. So for now I disabled ntp on that server and set time manually.
