Re: the tale of the time
Ok, this is a serious problem. I’m experiencing essentially the same thing. We’re running BP 1.1.3 and just upgraded form WPMU 2.8.6 to 2.9.1 . But as soon as I finished upgrading the entire site (including all the blogs), I went to the front page and everything is shown exactly 6 hours older than it really is.

I’ve done some digging around and this is what I’ve found so far: https://mu.wordpress.org/forums/topic/16374
I’ll be giving it a shot and see if I can make a simple hack like they mentioned.
