No, that timestamp is not a misprint

It is indeed 4:20 am. I have just finished totally redoing, from scratch and then copying out by hand, a group project so that it will be ready to hand in in less than 6 hours. And when I say I, I do mean me alone. Grrr. Yeah, there's a long story behind it, but I'll wait till I've had some scotch and some sleep before getting into it.
