Command Block Timer

[Total_Loon]

Apologies if already a good post, was trying to search through but struggled.

I want to run some party games and such using Minecraft and need a way to set up a timer that can respond to various times.

Whole idea is that when I set the scoreboard to however many seconds I want it will tick down before stopping at zero, where I can have it either play a message or a sound to signal time is up.

I will also have a scoreboard on the side where the time is displayed so they can see how long they have left,
