Regarding the new clock style:
For those who want the previous clock back without having to change anything else in the new build and without changing the current Home tab formatting should try installing this
White Clock that I found attached to another thread.
So far I can't find any problems, and it appears to perfectly restore the previous style clock. I have only had it installed for a few minutes, so I can't say for sure there are no side effects with installing it on 7/29, but it seems that way.
