Discworld fans know the irregular clock in Lord Vetinari's waiting room.
I just found out that there are building instructions out there how to build such a clock yourself - the source code is here https://github.com/akafugu/vetinari_clock
But it made me think: why don't we have a kernel patch that does this? Anyway I'm now reading up on the /dev/rtc class, NTP and PTP, wondering what would be funnier to do.
