Even with newer hardware, there are still weird date issues. The simple
fact that these GPSDO’s keep on running at all is a bit amazing.
Best to simply use the PPS from the GPSDO and get the date / hours /
minutes / seconds tag info by some other means. Let that “other means”
sort out leap seconds and all the other nonsense that is likely to tie things
We do have a GPS week zero coming up soon ….
