時間換算 一天24個小時 比如說2016-12-31 23:50：50 這個加上2小時要變分鐘 要變小時 變天 變月份 變年 還有就是減的時候 2016-1-1 0：00 減去2小時 也要都變 我想問的是 我下面中的代碼邏輯 是不是寫錯了 錯在那裡 求指導
對了 北京時間是utc +8 那 utc+3.5 是小時+3 分鐘 +5 還是+30 還是什麼
在線急等 謝謝 之前也問過 有哥 給我寫了另一個簡單方法 沒看懂 沒弄明白 所在又問了一遍
看我原來的那個帖子，獲取UTC時間字符串，每次計算都要 new 一個新的UTC事件，通過api更新時間對象後在調用方法設置時間，而不是直接操作
d.getUTCHours() + 3
這樣來操作，所以會顯示>24或者<0的情況出現
下面只改了部分，其他沒改的按照寫的示例修改
function updateDate() {
var d = new Date();
var a = d.getUTCHours();
//UTC時間字符串
var sUTC = d.getUTCFullYear() + '/' + (d.getUTCMonth() + 1) + '/' + d.getUTCDate() + ' ' + d.getUTCHours() + ':' + d.getUTCMinutes() + ':' + d.getUTCSeconds();
//世界標准時間
$("#time").val(d.getUTCFullYear() + "年" + (d.getUTCMonth() + 1) + "月" + d.getUTCDate() + "日 " + d.getUTCHours() + ":" + d.getUTCMinutes() + ":" + d.getUTCSeconds());
//當地時間
$("#time1").val(d.getFullYear() + "年" + (d.getMonth() + 1) + "月" + d.getDate() + "日 " + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds());
//惠靈頓時間
d = new Date(sUTC)//新UTC時間對象
d.setHours(d.getHours() + 12);
//因為是經過UTC計算得到的事件，就不需要在調用getUTCXXXXX這種方法了，直接調用getXXXX
$("#time2").val(d.getFullYear() + "年" + (d.getMonth() + 1) + "月" + d.getUTCDate() + "日 " + d.getHours() + ":" + d.getMinutes() + ":" +d.getSeconds());
//悉尼時間
d = new Date(sUTC)//新UTC時間對象
d.setHours(d.getHours() + 10);
$("#time3").val(d.getFullYear() + "年" + (d.getMonth() + 1) + "月" + d.getUTCDate() + "日 " + d.getHours() + ":" + d.getMinutes() + ":" + d.getSeconds());
