普通時間 → Unix時間戳

var commonTime = new Date(Date.UTC(year, month - 1, day, hour, minute, second))

laydate.render({
            elem: '#s_time',
            done: function(value, date, endDate){
                console.log(value)

                // 毫秒轉換成 秒 ，並減小8小時 時區，0點爲標準
                var commonTime = (Date.UTC(date.year, date.month - 1, date.date, 0, 0, 0) / 1000) - 28800;
                console.log(commonTime);
            }
        });

Unix時間戳 → 普通時間

var t = Math.round(new Date().getTime()/1000);

                var unixTimestamp = new Date(t * 1000);
                var n = unixTimestamp.getUTCFullYear();
                var y = unixTimestamp.getUTCMonth();
                var r = unixTimestamp.getUTCDate();
                
                ServiceProjectObj.Data.stime = n+'-'+(y + 1)+'-'+r;
                ServiceProjectObj.Data.scommonTime = (Date.UTC(n, y, r, 0, 0, 0) / 1000) - 28800;
