The clock is implemented as a driver for OS9, but underneath it's just
doing serial I/O with the bitbanger.  Some of the DriveWire functionality
has been added to non OS9 software, but I don't recall anyone doing the
clock specifically.  It's a probably a pretty simple hack if you have
source to any working driver, there are routines in hdbdos for the high
speed bitbanger I/O that can be called, I think you just send a couple
bytes then read the server's responding bytes which are the time according
to whatever is on the other end of the cable.  However, I doubt that any
existing rtc driver would be compatible since it's pretty different I/O
than you'd think a clock would use.
