Welcome, you hit the usual GPS week rollover issue, see these: <http://www.leapsecond.com/notes/gpswnro.htm> <https://www.febo.com/pipermail/time-nuts/2011-December/061725.html> No impact on the 10MHz/PPS accuracy. No command can correct the rollover, I seem to remember that if you set the date before the GPS has a fix (right after a power cycle), then the date will be correct (until the next power cycle). There is also this software: <http://www.ulrich-bangert.de/Z38XX.zip>
