Seems like this timestamp bug is bugging quite a few people. I noticed it earlier as well, but it was only fluctuating a few minutes, not 7 hours.

Also, finding that spaces in some of my posts are being unrecognized- I space my sentences right, but when it posts, all the sentences are cramped together- no spaces after periods, for example. If I try to edit the post, the space is actually there, however, meaning in those cases I have to put two or more spaces to get a single space to "stick".

This is a known bug, but only cosmetic. Nobody really knows just what is causing it, but you don't really have to worry about it. Since it only occures when the posted comment/forum post/whatever appears after submitting, you're the only one to see it like that. Any other time it will show up just as intended, without having to do anything. If your posts show up with spaces missing from here and there, just refresh.
