Last Weekend there was an mistake on the officiel game clock on the game Hamburg - Colone

On the last 16 sek. there was an mistake with the mechanismen and it runs in doppletime. Everybody in the stadium and on tv could see it.
Is there no way to overrule it and play the last down? Or it this clock tho one and only an the field?

Not sure what you are refering to, but the Line Judge has a back-up on his watch.
