It's probably 1024 weeks since a date was built into the firmware.
It's like the year 2000 problem. If you aren't worried about old people and
I tell you somebody was born in 03, you can assume that's 2003 rather than
1903. For GPS, a handy value for the cutoff is the date the firmware was
built. Any date that looks like it is older than the firmware is probably
off by a rollover.
