Bad news I'm afraid, timestamps will need to be removed. Due to the flatfile nature of this shoutbox (the shouts are cached in a single html file so database load is reduced when viewing the main page)
the timestamps will not be accurate for more than one timezone therefore there is little point in having them. If you want to see timestamps you can easily click "
Shoutbox" (at the top of the box) to take you to the shoutbox archive which does include proper timestamps as all the information is copied from the database.
Personally I don't see how timestamps are useful either - its just a message box...
