Sadly the RTC is around 100,000 ppm out - so can't be calibrated like that :(
I guess I could save the prescaler alongside the saved code, and could then load it at boot-time. It wouldn't be dynamic, but I guess it would actually make a really big improvement as I think the drift isn't that high - it's the change in frequency between individual chips that really sucks.
You could always solder a watch crystal on and it'll magically use that and make really good time :)
Good point about creating directories. I'll file a bug for it.
