最近项目需要计算两个时间戳相差的时间并返回具体的时间.上代码

  //封装计算距离奖励截止函数
    getRateEndTime(rateTime, newTime) {
      var tmp_time = newTime;
      var days = rateTime;
      var time = days - tmp_time;
      let day = parseInt(time / 3600.0 / 24);
      let hour = parseInt(
        (parseFloat(time / 3600.0 / 24) - parseInt(time / 3600.0 / 24)) * 24
      );
      let min = parseInt(
        (parseFloat(time / 3600.0) - parseInt(time / 3600.0)) * 60
      );
      let sec = time % 60;
      hour = hour < 10 ? "0" + hour : hour;
      min = min < 10 ? "0" + min : min;
      sec = sec < 10 ? "0" + sec : sec;
      //console.log(time);
      if (time < 0) {
        return "已结束";
      }
      if (time < 86400) {
        return `${hour} : ${min} : ${sec}`;
      }
      if (time > 0) {
        return `${day}天 ${hour} : ${min} : ${sec}`;
      }
    }

newTime 是当前的时间戳.

rateTime 是后台返回需要与当前时间戳比较的.

86400是一天的毫秒数.
