I'm a beginner and Ik this should be self explanatory but I just can't find one that doesn't require knowledge that I don't have.

Basically whenever I upload my runs to Youtube so they can be reviewed Youtube add a bunch of time because of delays. So I need a stopwatch to track my time properly on the screen so my runs actually count you know. If there are any suggestions that would be helpful, thanks.

Basically I accidentally wrote 4m 31s instead of 4m 42s because I'm an idiot. Idk how to correct my mistake. Does the person reviewing the run change it and accept it even though I was wrong?
