The FlyerTalk clock is always set to Colorado Springs time and always records posts by whatever time it is there when they come in. By coincidence, your home location happens to be on the same time during the winter months. Most of the world never is. My posts always show up as being made two hours earlier than I think they are, unless I'm traveling in which case they could be nearly anytime.
That's also why you see lots of posts made at weird hours of the morning. It's not a weird hour where they're made from; it just is in Colorado.
