太久远的版本，你只有自己测试看看js了。设置每1秒刷新

setInterval(function(){

const now = new Date();

const year = now.getFullYear();

const month = String(now.getMonth() + 1).padStart(2, '0');

const day = String(now.getDate()).padStart(2, '0');

const hours = String(now.getHours()).padStart(2, '0');

const minutes = String(now.getMinutes()).padStart(2, '0');

const seconds = String(now.getSeconds()).padStart(2, '0');

const formattedDate = year+"-"+month+"-"+day+" "+hours+":"+minutes+":"+seconds;

console.log(formattedDate);//可以把这个修改成赋值到控件或者单元格

}, 1000);
