JS处理时间戳问题

var Time = new Date((that.baseData.data.time) * 1000) //获取时间 that.baseData.data.time 是后端传过来的时间戳例如一串这个玩意：231654654 *1000是因为需要解决产生1970问题
 Y = Time.getFullYear() + ‘-‘;
 M = (Time.getMonth() + 1 < 10 ? ‘0’ + (Time.getMonth() + 1) : Time.getMonth() + 1) + ‘-‘;
 D = Time.getDate() + ‘ ‘;
 h = Time.getHours() + ‘:’;
 m = Time.getMinutes() + ‘:’;
 s = Time.getSeconds();
 that.baseDataTime = Y + M + D + h + m + s
 console.log(that.baseDataTime);
