Get Youtube Playlist Total Time
IMPORTANT
Due to how YT delivers content, going to a playlist from another page doesn't register as a change: Do either:
1. REFRESH THE PLAYLIST PAGE
2. OPEN PLAYLIST IN NEW TAB
IMPORTANT
A feature that youtube used to have but doesn't anymore for some reason.

If you feel the script is slow, it is deliberate, it loads all videos before calculating (like a script that calculates total playlist time should.) If you don't want to load all videos all the time I suggest just turning the script off when you're not interested in knowing the total.
