it's doing this to a lot of people, me included, but i wouldn't worry about it cuz it only shows up on the sidebar as 1:01 and when you click on the video it displays 1:00, however this is just for me and idk if it is for everyone. On another note they have a link of everyone's youtube video, so they will most likely just click on that and only see the 1:00. EDIT: @Domidude02
