Christian Benteke scored Belgium's opener in a World Cup qualifying record as his side comfortably maintained their Group H lead on goal difference.
The Crystal Palace striker held up six fingers in his muted celebration but was one second out with the official time standing at seven seconds.
Still, it set a new mark and his side were on their way to a rout.
To be fair, it was a gift for Benteke, who stole the ball after a defensive blunder from Gibraltar's defence at the kick-off before waltzing through for a simple finish.
