将以秒为单位的时间间隔转换为更易理解的形式

在Royi的帮助下，我们获得了 以人类可读形式输出时间间隔的 代码：

function millisecondsToStr (milliseconds) {    // TIP: to find current time in milliseconds, use:    // var  current_time_milliseconds = new Date().getTime();    function numberEnding (number) {        return (number > 1) ? 's' : '';    }    var temp = Math.floor(milliseconds / 1000);    var years = Math.floor(temp / 31536000);    if (years) {        return years + ' year' + numberEnding(years);    }    //TODO: Months! Maybe weeks?     var days = Math.floor((temp %= 31536000) / 86400);    if (days) {        return days + ' day' + numberEnding(days);    }    var hours = Math.floor((temp %= 86400) / 3600);    if (hours) {        return hours + ' hour' + numberEnding(hours);    }    var minutes = Math.floor((temp %= 3600) / 60);    if (minutes) {        return minutes + ' minute' + numberEnding(minutes);    }    var seconds = temp % 60;    if (seconds) {        return seconds + ' second' + numberEnding(seconds);    }    return 'less than a second'; //'just now' //or other string you like;}
