毫秒转换日期格式

function changeTime(time){
if(time){
var oDate = new Date(time*1),
oYear = oDate.getFullYear(),
oMonth = oDate.getMonth()+1,
oDay = oDate.getDate(),
oHour = oDate.getHours(),
oMin = oDate.getMinutes(),
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;
}
return num;
