I installed this update last night, and I've only seen 2 differences so far, both bad.
The first, which you mentioned, is that it changed the time and time zone I had set.
The second is the loss of a feature I liked. I had a folder of .jpegs in the "image" directory, and when displaying one you could go to the next file just by pushing the down or right arrow. That no longer works; now you have to back out of the file and choose the next one from the list. So I'm not happy with the change.
