批次扩展后的拍卖计时器问题

Question

我正在asp.net的拍卖网站上工作。当我们点击每个批次的增量出价按钮时，如果计时器中的时间少于3分钟，那么批次时间会延长3分钟，但每个批次的计时器会在几秒钟内失配，而我的客户不希望这样。

这是调用JS函数来扩展批次的时间：

eval('timer' + auctionLotId).cdtime('timer' + auctionLotId + "', '" +    auctioncurrtime + "', '" + auctionendtimer + "', " + auctionLotId);

这是用于更新计时器的JS文件：

function cdtime(container, currentTime, targetdate, AuctionLotID) {
    if (!document.getElementById || !document.getElementById(container))
        return;
    this.container = document.getElementById(container);
    this.auctionLotID = AuctionLotID;
    var now = new Date();
    //this.currentTime = new Date(now.getFullYear(), now.getMonth(),     now.getDate(), now.getHours(), now.getMinutes(), now.getSeconds());
    //this.currentTime = new Date(now.getUTCFullYear(), now.getUTCMonth(),    now.getUTCDate(), now.getUTCHours(), now.getUTCMinutes(), now.getUTCSeconds());
    this.currentTime = new Date(currentTime);
    this.targetdate = new Date(targetdate);
    this.currentTime.setSeconds(this.currentTime.getSeconds() - 1);
    //alert('currentTime: ' + this.currentTime);
    //this.targetdate = new Date(now.getUTCFullYear(), now.getUTCMonth(),  now.getUTCDate(), now.getUTCHours(), now.getUTCMinutes(), now.getUTCSeconds());
    this.timesup = false;
    this.updateTime();
}
cdtime.prototype.resetTimer = function (newdate) {
    var thisobj = this;
    this.targetdate = new Date(newdate);
    this.extended = 1;
    this.timesup = false;
    //this.updateTime(); 
}
cdtime.prototype.updateTime = function () {
    //alert(this.currentTime);
    var thisobj = this;
    this.currentTime.setSeconds(this.currentTime.getSeconds() + 1);
    this.tim = setTimeout(function () { thisobj.updateTime() }, 1000); //update time every second
    //timer = setTimeout(updatetimer, 1000);
 }
