nodejs 服务端时间问题

nodejs构建的服务端，由于时区的问题会导致返回的日期不正确，为了修正日期问题，对Date增加全局的toJSON方法来修正此问题，代码如下：
注：如果使用的是express框架，则在app.js的首部增加如下代码，其他框架根据实际情况贴入即可
Date.prototype.toJSON = function () {
  var timezoneOffsetInHours = -(this.getTimezoneOffset() / 60); //UTC minus local time
  var sign = timezoneOffsetInHours >= 0 ? '+' : '-';
  var leadingZero = (Math.abs(timezoneOffsetInHours) < 10) ? '0' : '';

  //It's a bit unfortunate that we need to construct a new Date instance
  //(we don't want _this_ Date instance to be modified)
  var correctedDate = new Date(this.getFullYear(), this.getMonth(),
      this.getDate(), this.getHours(), this.getMinutes(), this.getSeconds(),
      this.getMilliseconds());
  correctedDate.setHours(this.getHours() + timezoneOffsetInHours);
  var iso = correctedDate.toISOString();//.replace('Z', '').replace('T',' ').replace(/.[d]+/g,'');

  return iso;
};
