For the clock, I've in this way, added +2 hours at the time set in the Sony Firmware... now is OK... it is no-sense but it works
I've tried the same cbz converted in EPUB, here there is something wrong: the size of the image is very little (smaller than reading it as zip/cbz) and there is no way to resize it! The size change let my choose fonts size NOT image size... if I try it application die, obviusly (the operation is invalid

).
It is very slow to load the file to... 1-2 minutes at least
I've tested more the zip/cbz thing and I think if the zoom was functional the results would not be so bad (maybe best that epub converted as these are the original NOT ricompressed/modified images)... the thing should be similar in functionality at the pdf reader if the image is zoomed should possible to navigate with up & down arrows.
The technology is already here (the rectangle is present!) but zoom do nothing...
Well I think we have to wait that the software is more polished...
