I think you misinterpret my statement.

I mean that U-Boot is just a boot loader,  used  mostly  in  embedded
systems  which often run in 24/7/365.25 mode. Only a tiny fraction of
the total system time will ever be spent in U-Boot. Chances that  the
roll-over happens while an OS (or some other software) is running are
magnitudes bigger than that we see this event in U-Boot.

So calculate the probability that (1) the same hardware will still be
used in 2094, (2) it will still run U-Boot,  and  (3)  the  roll-over
happens exactly during a reboot of the system.

Now how much effort do you intend to spend on solving such a problem?

My recommendation is: document and ignore it. It's a  feature  (read:
limitation) of the hardware, and this type of hardware will go out of
existence soon enough.

Best regards,

Wolfgang Denk

The use of Microsoft crippleware systems is a sin that  carries  with
it its own punishment.
