JS代码【时间计算】

    // 运行时间 by.灵心云 ->cloudlx.top
//运行时间
window.setTimeout("siteTime()", 1000);

function siteTime() {
    window.setTimeout("siteTime()", 1000);

    const X = new Date("11/21/2022 5:20:00");
    const Y = new Date();
    const T = (Y.getTime() - X.getTime());
    const M = 24 * 60 * 60 * 1000;
    const a = T / M;
    const A = Math.floor(a);
    const b = (a - A) * 24;
    const B = Math.floor(b);
    const c = (b - B) * 60;
    const C = Math.floor((b - B) * 60);
    const D = Math.floor((c - C) * 60);

         document.getElementById("sitetime").innerHTML = A + " 天 " + B + " 小时 " + C + " 分钟 " + D + " 秒";
