Nope, I tried all the resets I could find, I can set the date right but as soon as the Z3815A sees a bird, it jumps back to 1993.
How annoying, Anyone else with a Z3815A having problems?

I have 5 Z3805A and only one had the wrong date.
They all have identical GPS modules and firmware so I don't know why just one decided to warp back to 1993.

The Z3815A is still stuck at 1993, I can't even set it to 11 Aug 2007. (-1024) even with antenna unplugged and power cycle.
I mean, Can set it to 11 Aug 2007, but after the 1st bird it sees it goes back to 1993.

I might try a factory default and see how we go.

I just checked by Z3801A which is being monitored by SatStat on an old laptop. Mine is showing the correct date and time.
