It's not just the pilots that have to hit a TOT, it's usually the folks singing/playing the national anthem. It's pretty tough to get them to understand that they need to 1) start it at an EXACT time and 2) sing it the same way they practiced, i.e. not draw out notes...in order to finish at an exact time. I was the dude on the ground for one recently...they started singing a minute early and sang it in 30 fewer seconds than they did in practice. Kind of tough to fix all the timing when you're holding just 10 miles away without busting some windows with a sonic boom.
