I'm sure you know all this but if LiveJournal doesn't know anything about your timezone (or you are viewing in a style that doesn't do timezones) then it will display comment timestamps in GMT (http://www.livejournal.com/support/faqbrowse.bml?faqid=156). However, the time on a journal entry is whatever time the poster typed into the relevant field (and if they didn't then it's usually auto-filled with the poster's local time).
