It's quite old, but a match to the double Neff Oven.

The time display goes blank after use. Otherwise it works normally for
setting the operating time. Press stop, and it appears at 12.00. Can then
be set and works normally, until the unit is used again.

Is there an internal battery that might have failed? It is never powered
down.

I wouldn't have thought so. Cookers are amongst the most annoying white
goods that forget the time whenever there is a short powercut.

They then choose either:

to restart as if from midnight 1/1/1980
or
flash 00:00 and refuse to do anything until you set the system clock.

We have one in each camp and of the same brand so it is possible to
infer both that there has been a power cut and also how long ago.
