With current xen-3.1-testing tip (which is basically not much different from
-rc2) I find the localtime option works fine for me. What I did was change
my dom0 timezone to US Pacific, then create a domU with 'localtime=1' in its
config file, and then create a domU with no localtime config. The former
showed output in 'date' 8 hours behind the 'date' output of the latter. The
guests were created using the usual 'xm create <config file>' method.

Are your dom0 user-space tools definitely up to date?
