Thanks for the link.  Now I see.

The Annex defines Yet Another Binary ToD message.

I don't see ts2phc supporting dozens and dozens of different binary
ToD format.

Instead, I would write a stand alone program that groks the Binary ToD
and serves standard NMEA RMC sentences on a local TCP port.

Then configure ts2phc by setting

        ts2phc.nmea_remote_host
        ts2phc.nmea_remote_port

appropriately.

(This is exactly the approach I am using to support some random GPS
device that doesn't produce usable RMC sentences.)

Thanks,
Richard
