Forum time?

I think I just noticed some time weirdness? When I opened up the site page, not logged in, it was set to ET minus 2 hours. As soon as I logged in, all the times reset to ET minus 1 hour. I need to repeat this to make sure I didn't mistake something, but I think that's what just happened. That may explain a sense of time warp that I've sometimes had, but couldn't explain.
