As seen on lj_dev, LiveJournal is adding timezone support. So go edit your user info to include your timezone. By setting your timezone, it let you see more information in the comments of posts. Check out a post with comments and you'll see the comment says something like "+1 hour" if the comment was added an hour after the original post. There's a tooltip associated with that text, so if you hover your mouse over it, you'll get a popup that tells you the exact time it was posted -- both for the person who posted it, and for you. Kinda cool.
