A few years ago, I did a similar clock for use in the car, but using a 4 line lcd. I never 
thought about correcting it for the software delays- an excellent idea Bert, thanks. I 
guess I am going to have to do a bit of a re-write sometime soon. Thinking about it, I 
could just feed the 1pps into the pic and use that to trigger the display update but with 
one second added.

If anyone is interested, the clock is here

and if anyone wants the source code (it's in crownhill pic basic) I'm happy to supply it.

I elected to design my own clock display instead. Mine is fed by a Garmin GPS-35 GPS and it uses a 64 x 8 LED array for the display. It is driven by a PIC18F1220 with custom firmware.
