js中unix时间格式化为时分秒格式

/**unix时间差（秒时间差）转化*/
function unixPoorTrans(trasData){
    var hour,min,sec;/**时、分、秒*/
    var transTM = new Date();/**声明js日期变量*/
    var transedTM="";
    transTM.setTime(trasData*1000);/**初始化js日期*/
　　
　　/**得到时、分、秒，并重新组装时间*/
    (transTM.getHours()-8) < 10 ? hour = '0' + (transTM.getHours()-8) : hour = transTM.getHours()-8;
    transTM.getMinutes() < 10 ? min = '0' + transTM.getMinutes() : min = transTM.getMinutes();
    transTM.getSeconds() < 10 ? sec = '0' + transTM.getSeconds() : sec = transTM.getSeconds();
    if(hour != '00')    transedTM += hour+"小时";
    if(min != '00')    transedTM += min+"分";
    if(sec != '00') transedTM += sec+"秒";
    return transedTM;
}
