毫秒整数转化为时分秒（例如：毫秒整数转换为00:30:00）

var MillisecondToTime = function (msd) {
        var time = parseFloat(msd) / 1000;
        if (null != time && "" != time) {
            if (time > 60 && time < 60 * 60) {
                var a = parseInt(time / 60.0) < 10 ? ('0' + parseInt(time / 60.0)) : parseInt(time / 60.0);
                var ms = parseInt((parseFloat(time / 60.0) - parseInt(time / 60.0)) * 60);
                var b = (ms < 10) ? ('0' + ms) : ms;
                time = '00:' + a + ':' + b;
            }
            else if (time >= 60 * 60 && time < 60 * 60 * 24) {
                var H = parseInt(time / 3600.0) < 10 ? ('0' + parseInt(time / 3600.0)) : parseInt(time / 3600.0);
                var ms = parseInt((parseFloat(time / 3600.0) - parseInt(time / 3600.0)) * 60);
                var M = (ms < 10) ? ('0' + ms) : ms;
                var ss = parseInt((parseFloat((parseFloat(time / 3600.0) - parseInt(time / 3600.0)) * 60) -
                    parseInt((parseFloat(time / 3600.0) - parseInt(time / 3600.0)) * 60)) * 60);
                var S = (ss < 10) ? ('0' + ss) : ss;
                time = H + ':' + M + ':' + S;
            }
            else {
                var d = parseInt(time) < 10 ? ('0' + parseInt(time)) : parseInt(time);

            }
        }
