Well indeed progress the dc468 is now sync'ing to gps on start. Have a dirty fudge factor to get the seconds exactly synced. Don't like it but does work. Did try to use hex as a month indicator and that did not work. As an example Nov would be A and Dec B. But looking at the driver ckts its doesn't look like anything stops you from doing it. I have seen the clock put out a-d in the digits when I had the info feeding them wrong. Need to tinker with that a bit more. I just don't find 100s of days to be useful though easily implemented now that I can get the date. Regards Paul.
