Is it possible that you would allow users to specify the way times are displayed in the forum? I'd really like to see times in 24-hour rendition rather than 12-hour. That is, instead of 7:45 PM, I'd prefer to see 1945 or even 19:45.
Also, before login, times appear to be displayed in UTC. Is that the intent? Can it be changed to use the user's time zone?
