时间戳获取当前时间 并转化格式

//如果是求当前时间只需去掉time形参即可,time 为时间戳;

function getNowDate(time){

     var nowDate -new date(time);

       var month = putZero(nowDate.getMonth()+1),

            day = putZero(nowDate.getDate()),

            hour = putZero(nowDate.getHours()),

            min = putZero(nowDate.getMinutes()),

            sec= putZero(nowDate.getSeconds());

            return nowDate.getFullYear()+'-'+month+'-'+day+'   '+hour+':'+min+':'+sec;

}

//为个位数加0

function putZero(num){

        return num<10?'0'+num:num;

}
