Take a look at
http://clippingsconverter.com for managing your Kindle clippings. It imports and organizes your "My Clippings.txt" and makes it much easier to view your notes and stuff.
Regarding the time: the Kindle will reset the time back to the hardware settings when it reboots, but fixes itself when connected to WiFi.
There should be a way to fix it via the Jailbreak plus
KindleTerminal (kterm). Requires
KUAL.
This may be a little too geeky, though.
