It says 9:03 MST, too (mine, at least).
Haha!
I figured it out. Twatter changed my timezone on me.
That's rather curious by itself.
Yes. Twatter switched my timezone to PST from MST. No idea why, but they did. I didn't notice until I saw the post from an anon about it being off for him as well. I'm sure glitches and bugs can do this, but I've never had it happen before (and I'm always logged in).
