I believe 11/22/28 was the default date stored in the internal hardware
clock on the 400.  Of course, with recent support for Year 2000 added
you ended up with the wonderful side benefit of it being interpreted as
2028 instead of 1928.  
As for why 11/22/28 - something to do with how the date is stored
internally - I forget the details.

You could also run across this problem if certain hardware on the AS/400
was replaced (the control panel I believe).  The next IPL would take
this default date and your system would come up as 11/22/28.
I ran across this myself once a few years ago.
They issued PTF's that would blank out this default date in this case
and force the operator to enter a date/time during IPL.

I know the V2R3 PTF was SF15305.
I believe in V3R0M5 & V3R1M0 there were instances where the date would
default to 95/01/01, and there were PTF's issued for this, for V3R0M5
the current PTF is MF09401 and for V3R1M0 it is MF09265. 
Original PTF was MF08828 for V3R0M5 and MF08829 for V3R1M0 and you will
probably need to see the cover letter for those for details instead of
the above superseding PTFs.

Haven't seen any PTF's for later releases.  Maybe the problem has been
fixed in the base code for V3R2 + ?
Although I suspect it is still a problem with the RISC models.
APAR MA15728 shows they know there's a problem, but there appears to be
no solution at the moment.

Jim - do you know what release this customer was running ?
