[time-nuts] Tymserve 2100 thinks it's 1995?

[Chris Mottram]

Hi Bob, I've just this minute joined this list, because I Tymserve 2100 
unit we have at work has just started doing the same thing, at just gone 
1am UT on May  3rd. I've also tried restarting and power cycling (this 
is somewhat convoluted as the unit is ~3000 miles away from me) but it's 
firmly stuck in 1995

Ours is currently running Rev 3.1 :
5 ? version
Boot Code - Tymserve_2100
   Rev 1.1   12/20/1996 13:07:21
Main Code - TymServe_2100
   Rev 3.1   08/22/2002 12:15:37

After a power cycle, our unit comes up as follows:
3 ? time
JAN 01 1995 00:01:53.687252
After the GPS has locked this changes to:
5 ? time
SEP 17 1995 20:14:35.479915
Where 20:14 was the correct UT time.

cheers

Chris

I haven't caught it dropping back, so i don't know if it's doing this on the hour, after an hour, or what, but I noticed it last night, and I've restarted it a few times today.
