Kevin.
Please please, please say additional or extra or injury or added-on or appended or spare or supplementary. Seconadry time, dependent time, reserve time, over and above time.
Pick one of those words, whichever one sounds nicest.
Just please stop saying "playing time". You don't even say "added playing time". Just "playing time" and everytime I hear it I cringe because it sounds childish and moronic and as if the announcer doesn't know the time quota of a football match.
Can you understand what I'm saying?
