js利用时间戳动态显示系统时间距指定时间的时间差

function dateTimes(times) {
????var d = new Date(times * 1000);
???var date = (d.getFullYear()) + "-" + (d.getMonth() + 1) + "-" + (d.getDate()) + "-" + (d.getHours()) + ":" + (d.getMinutes()) + ":" + (d.getSeconds());
???var startTime = date;
???????var currTime = new Date(); //当前时间 ?
???????//将xxxx-xx-xx的时间格式，转换为 xxxx/xx/xx的格式 ?
???????startTime = startTime.replace(/\-/g, "/");
???????var sTime = new Date(startTime);
???????var totalTime = currTime.getTime() - sTime.getTime();
???????var days = parseInt(totalTime / parseInt(1000 * 60 * 60 * 24));
???????totalTime = totalTime % parseInt(1000 * 60 * 60 * 24);
???????var hours = parseInt(totalTime / parseInt(1000 * 60 * 60));
???????totalTime = totalTime % parseInt(1000 * 60 * 60);
???????var minutes = parseInt(totalTime / parseInt(1000 * 60));
???????totalTime = totalTime % parseInt(1000 * 60);
???????var seconds = parseInt(totalTime / parseInt(1000));
???????var time = "";
???????if (days >= 1) {
???????????time = days + "天" ;
???????} else if (hours >= 1) {
???????????time = hours + "时";
???????} else if (minutes >= 1) {
???????????time = minutes + "分"
???????} else {
???????????time = seconds + "秒";
???????}
