Katie,

I'm surprised your Kobo didn't automatically adjust for daylight savings time. Mine did though I rarely connect to Wi-Fi*

I did have to do a complete factory reset when my Wi-Fi firmware update screwed up though. Using Calibre to manage my Kobo saved my bacon there. The sideloaded books were still on the SD card and plugging the Kobo in to Calibre redid my collections. All I lost were my reading stats.

For the amount of work you obviously put in to your library, I really don't understand why you don't use Calibre. It is useful for just this sort of situation.

*I do leave Wi-Fi enablled. I just don't sync ever.
