Time zone of System Image Recovery

Hi all,

My server OS is Windows Server 2008 R2 (EN). But I set the time zone as China time (UTC +8:00) in the Windows already. One day, I wanted to recover my system in PE. So I inserted the Windows Server 2008 R2 disc into the DVD-ROM, and then booted from the DVD. Then I set the Time and currency format to Chinese (Simplified, PRC), but the time zone didn't chang to China time (GMT +8:00) automatically, it was still showing GMT -8:00 (PST). Can I fix it?

Thanks,
