求》修正时间计算，这个代码时间计算是错误的


function lovetime() {
    window.setTimeout("lovetime()", 1000);
    var seconds = 1000
    var minutes = seconds * 60
    var hours = minutes * 60
    var days = hours * 24
    var years = days * 365
    var today = new Date()
    var todayYear = today.getFullYear()
    var todayMonth = today.getMonth()
    var todayDate = today.getDate()
    var todayHour = today.getHours()
    var todayMinute = today.getMinutes()
    var todaySecond = today.getSeconds()
    // 修改这里时间即可 我的是2018.11.19
    var t1 = Date.UTC(2020, 5, 23, 00, 00, 00)
    var t2 = Date.UTC(todayYear, todayMonth, todayDate, todayHour, todayMinute, todaySecond)
    var diff = t2 - t1
    var diffYears = Math.floor(diff / years)
    var diffDays = Math.floor((diff / days) - diffYears * 365)
    var diffHours = Math.floor((diff - (diffYears * 365 + diffDays) * days) / hours)
    var diffMinutes = Math.floor((diff - (diffYears * 365 + diffDays) * days - diffHours * hours) / minutes)
    var diffSeconds = Math.floor((diff - (diffYears * 365 + diffDays) * days - diffHours * hours - diffMinutes *
        minutes) / seconds)
    document.getElementById("lovetime").innerHTML = "我们已经在一起 " + diffYears + "年" + diffDays + "天" +
        diffHours + "小时" + diffMinutes + "分钟" + diffSeconds + "秒啦"
}
lovetime()

跑了下代码，用webstorm跑的， var t1 = Date.UTC(2020, 5, 23, 00, 00, 00)在我这直接报错了。每年直接定死了365天计算也是会存在误差的。你可以参考下这个代码

function GetDateDiff(startTime, endTime, diffType) {
    //将xxxx-xx-xx的时间格式，转换为 xxxx/xx/xx的格式
    startTime = startTime.replace(/\-/g, "/");
    endTime = endTime.replace(/\-/g, "/");
    //将计算间隔类性字符转换为小写
    diffType = diffType.toLowerCase();
    var sTime =new Date(startTime); //开始时间
    var eTime =new Date(endTime); //结束时间
    //作为除数的数字
    var timeType =1;
    switch (diffType) {
      case"second":
        timeType =1000;
        break;
      case"minute":
        timeType =1000*60;
        break;
      case"hour":
        timeType =1000*3600;
        break;
      case"day":
        timeType =1000*3600*24;
        break;
      default:
        break;
    }
    return parseInt((eTime.getTime() - sTime.getTime()) / parseInt(timeType));
  }
  alert(GetDateDiff("2018-11-19 10:30:22","2020-08-23 10:38:22","day"));
