时间搓转化为时间

let time=1493098173；

getTime(time){
    let date = new Date(time);
    let Y = date.getFullYear() + '-';
    let M = (date.getMonth()+1 < 10 ? '0'+(date.getMonth()+1) : date.getMonth()+1) + '-';
    let D = date.getDate() + ' ';
    let h = date.getHours() + ':';
    let m = date.getMinutes() + ':';
    let s = date.getSeconds();
    return (Y+M+D+h+m+s);
}
