xen discuss - Mar 2009 - xen passing incorrect time?

Here''s what I did. To make my xvm server as similar as possible to
Linux dom0, one of the changes I did was setting hardware clock to use
UTC by changing /etc/rtc_config like this

zone_info=UTC
zone_lag=0

/etc/TIMEZONE already have this entry

TZ=Asia/Jakarta

(which is equal to GMT+7, btw). Time in dom0 is synchronized using NTP.
On windows domU''s config file (in old xen config format), I have this

localtime=1

which works correctly on Linux dom0s. However on opensolaris this
makes Windows domU shows incorrect time (7 hours too late). WITHOUT
the "localtime" line, domU is further late (14 hours too late).

So what I had to do was having the

localtime=1

as well as

rtc_timeoffset=25200

(which is 7 hours, in seconds). Is this a known bug, or is there
something wrong with my setup?

This isn''t a good idea. You''re seeing:

6781924 xVM sending UTC hwclock to domU as UTC hwclock-localtime.offset
