[xwiki-users] Why the "created" and "last modified" time are wrong?

Hi All, I have installed "XWiki Enterprise 2.2.1.27354" on my laptop, and found that after created or modified the document, the "created" and "last modified" time are wrong! For example, my local time is "2010/04/28, 22:08", but the "date" of the document I just created is "2010/04/28, 09:38". My local time zone is "Beijing, China", UTC/GMT +8 hours. How could I solve this issue? You comments are welcome! Island
