The display issue is likely happening elsewhere in Calibre. I've seen it once, but it worked correctly later. Odd.
The timezone stuff was an actual bug, but it should be pretty much fixed at this point.
I've got another patch to clean up behavior of the author field to be consistent with other devices and Calibre, but have the option to get the Sony behavior as well. The periodical detection doesn't work in the latest version of the driver, but that will likely be addressed next week unless there's a demand for it any sooner.
I've also been playing around with changing the Sony behavior by editing the SQLite DB. I've got one hack working that I've posted up in the Sony Dev forum (not Calibre related) for those adventurous enough. I managed to turn the "Recently Added" list into a "Recently Added or Opened" list.
