js中格式化时间戳

//将时间戳格式化 
function getMyDate(time){  //time为时间戳
    if(typeof(time)=="undefined"){
        return "";
    }
    var oDate = new Date(time),  
     oYear = oDate.getFullYear(),  
     oMonth = oDate.getMonth()+1,  
     oDay = oDate.getDate(),  
     oHour = oDate.getHours(),  
     oMin = oDate.getMinutes(),  
     oSen = oDate.getSeconds(),  
     oTime = oYear +'-'+ getzf(oMonth) +'-'+ getzf(oDay) +' '+ getzf(oHour) +':'+ getzf(oMin) +':'+getzf(oSen);//最后拼接时间  
            
     return oTime;  
    };
    
     //补0操作,当时间数据小于10的时候，给该数据前面加一个0  
    function getzf(num){  
        if(parseInt(num) < 10){  
            num = '0'+num;  
        }  
        return num;  
    }
