There is a realy cheap DCF77 clock receiver (called PCDCF) available from
Conrad electronics here in Germany. It plugs into a parallel port. The
protocol is documented, so writing a driver was easy.


A kernel driver (patch to sys/dev/lpt.c) and patches for the in-tree xntp
version are available from
and a userland tool to check it's battery status, receive quality etc

I'm going to submit the xntp patches back to the xntp maintainers too.
