[time-nuts] Warped back to 1993

[Mark C. Stephens]

Okay this is what worked for me:

1. Removed power and antenna.
2. apply power with no antenna.
3. send :GPS:INIT:DATE 2007,08,11
4. plug antenna back in.

For some reason if I used the correct date, the Z3815A warped back to 1993.

But I am curious why did this happen today?

Hal, I can't get it to take, I keep getting E-350 and the time does not change.
Did you unplug the antenna or anything while you changed date?

Is that off by 1024 weeks?  (Looks close, but I haven't checked the details.)

There is a week field in the GPS data stream.  It's only 10 bits.

I had that problem on a Z3801A.  It did the right thing after I told it the date.
  :GPS:INIT:DATE 2011,12,26
