PRS300 and PRS+ font and clock questions

[jlbfoot]

I have successfully flashed my 300 with the PRS+ hack. Searching the forums, I cannot find how to change the default Epub or LRS font. The info that I have found relates to a 505 and a 350. I would like to modify the fonts for both Epub's and LRF's if possible. I use Calibre and will delve into css if necessary. Can someone point me in the right direction?

One other thing. My clock looks funny in 12 hour format. It's something like...
6...kpm or such (I don't have my reader with me at present). The 24 hour format is fine. I flashed on top of a borda flash...could that be the problem? Everything else seems to work fine, although I've only had a day to play with it. Thanks!
