[time-nuts] GPS week wrap in HP Z3801A

I turned on a Z3801 that had been idle for a while. The status screen said:
UTC 20:03:44 [?] 11 May 1992
That looks like 1024 weeks (19.7 years) ago.
When I first turned it on, before finding any satellites, it said:
UTC 12:05:00 [?] 01 Jan 1992
Has anybody else noticed troubles like this?
I've got another one that still works. It's got a bigger serial number so I
assume it's more recent.
Does anybody know how to read the firmware date or version? There is a
command to get info from the GPS unit, but I haven't found a way to get any
info for the main firmware.
After a while, the "[?]" goes away.
These are my opinions, not necessarily my employer's. I hate spam.
