quick javascript function to fetch youtube timestamp from livestream, for pasting into devtools

getURLTime.js

(function getURLTime() {
    const params = (new URL(document.location)).searchParams
    if(params.has('v')) {
        const v = params.get('v');
        const ytplayer = document.getElementById("movie_player");
        const t = Math.round(ytplayer.getCurrentTime())
        const newUrl = `https://youtu.be/${v}?t=${t}`;
        return newUrl;
    }
    return document.location;
})()

Prepend with "javascript:" in the URL section of a chrome bookmark. This script allows me to fetch the current timestamp of a youtube livestream while it is broadcasting
