Reseted it how? Nothing short of a true, full, manual factory reset (i.e., via the button trickery during boot, or the dev menu) will truly clear everything off.
I don't really see any way of something like that happening unless you have multiple instances of *Clock running, and you *cannot* run two instances of NanoClock concurrently (it's a technical limitation, subsequent copies will abort on launch).
As for NanoClock itself, it also *cannot* merrily jump between state, it's a
simple branch: it either uses the truetype font, or it doesn't.
