毫秒转换日期格式

function changeTime(time){
if(time){
var oDate = new Date(time*1),

oSen = oDate.getSeconds(),
oTime = oYear +'-'+ getBz(oMonth) +'-'+ getBz(oDay) +' '+ getBz(oHour) +':'+ getBz(oMin) +':'+getBz(oSen);//拼接时间
return oTime;
}else{
return "";
}

}
//补0
function getBz(num){
if(parseInt(num) < 10){
num = '0'+num;
}
