yeah. it's just that a mega was mentioned. and all that flash. then i realized how large the files actually were and that all that flash wasn't, in fact, all that much
If you stored all possible clock digits, including background, on the SD, you would do your updates by writing a bitmap instead of writing text.

Might take a couple of minutes to do them all, but I'd only have to do it once a day at a maximum.
