Timezone for Boards?

I just posted a topic in the iOS Programming (ed. 5) board around 10 PM my time (US EST – which is what my board preferences are set to) Friday and it showed up as posted 12:01 AM Saturday. Is the server sitting on a rocky island out in the mid-Atlantic?

And this post was put up 10:44 PM Friday – it shows as 12:08 AM!
