获取当前时间

function getNowTime() {        
      var date = new Date();        
      this.year = date.getFullYear();        
      this.month = date.getMonth() + 1;       
      this.date = date.getDate();        
      this.hour = date.getHours() < 10 ? "0" + date.getHours() : date.getHours();        
      this.minute = date.getMinutes() < 10 ? "0" + date.getMinutes() : date.getMinutes();       
      this.second = date.getSeconds() < 10 ? "0" + date.getSeconds() : date.getSeconds(); 
      this.milliSeconds = date.getMilliseconds();        
      var currentTime = this.year + '-' + this.month + '-' + this.date + ' ' + this.hour + ':' + this.minute + ':' +this.second;        
      return currentTime;    
}

时间戳转日期

function time(timestamp) {        
    var date = new Date(timestamp * 1000);//时间戳为10位需*1000，时间戳为13位的话不需乘1000        
    var Y = date.getFullYear() + '-';        
    var M = ((date.getMonth() + 1) < 10) ? ('0' + (date.getMonth() + 1) + '-') : ((date.getMonth() + 1) + '-');        
    var D = (date.getDate() < 10) ? ('0' + date.getDate() + ' ') : (date.getDate() + ' ');        
    var h = (date.getHours() < 10) ? ('0' + date.getHours() + ':') : (date.getHours() + ':');        
    var m = (date.getMinutes() < 10) ? ('0' + date.getMinutes() + ':') : (date.getMinutes() + ':');        
    var s = (date.getSeconds() < 10) ? ('0' + date.getSeconds()) : (date.getSeconds());        
    return Y + M + D + h + m + s;   
 }
