Question: backBlog config

BackBlog comments claim to be GMT, but as I only just noticed, they're not--unless it's Daylight Savings right now, or something. I'm in EST, which is GMT - 5:00, but when I post a comment it lists its time as only four hours later. For instance, I just posted a comment on "Look, Behind You" that lists its timestamp as 17:38 GMT; it should have been 18:38.

I only started noticing it now that we have to keep track of how long it's been since the last bid on a Super-Power. Can anybody else confirm this disparity? If so, is there a way to fix this in the backBlog configuration?
