This is very strange. It looks like the time reported by the GPS
is suddenly off by ~14.4 hours.

And here it is almost exactly 24 hours off.
I think that indicates a firmware bug in the GPS. Is there a firmware
update you could apply?
I'd suggest to ask on the gpsd-users mailing lists and see if anyone
has experience with this device.
