GMT, actually. 2am (US Central time) on Sunday is usually when I finish writing articles, for some reason, and they immediately get upvoted when I submit at that time.
When I submit on weekday afternoons (my time), the articles get about 1 upvote (and then I delete them so I can try again later, heh).
