Surely, I will write them up and post them. My current plan of action is to configure ntp on a pair of Linux machines, using one as a server so that I can sync to it when I'm not connected to the inet. Then I will try to sync up the Hurd box and one of the Linux boxes. The Hurd box and Linux box share a single physical manifestation (or infestation my wife would say). I want to try this two step process since I have not idea how ntp works in practice.
